ABSTRACT: The feasibility of continuous photometric characterization of the ad-
hesion of nickel-plating to a metal base during the electroplating process was
examined. After focusing a light beam an an electrode surfaco subjected to elec-
trolytic nickel-platl,,ig the intensity of the reflected light was measured photo-
metrically. The nickel plating reflectivity and polarization were measured in an
electrolyte containing# 300 g1l,Of Ni8O4*7H2O, 60 g/1 Of NIC12#6HZO, and 38 g/1
, and at 250C. The nickel,
Of H3BO3; at pH = 3, with a current density of 40 mA/cm2
platings ware deposited an passLvated (immersed for 20 sec in a chromic acid--
250 g/1) or activated (immereed in 5% H2SO4) nickel and steel electrodes. The

change in reflectivity and polarization during the process of nickel-plating of
steel samples is shown in fig. 1 of the Enclosure. The electrode surface activity
and the strength of adhesion of nickel plating is well characterized in terms of
reflectivity decline after the initial current switch-on. The strength of the
plating-base adhesion is determined by the photometric method more accurately than
by either mechanical or electrochemical methods. It is found that passivation
with chromic acid impairs the adhesion strength. Orig. art. has: 3 figures.

ABSTRACT: The article describes an attempt to produce bright copper deposits
by anode treatment with a current pulse in a pyrophosphoric acid electrolyte
used for electroplating. The reflecting power of the copper deposit was studied
in the electrolysis process with a photometer developed in the Institute of Physical
Chemistry of the AN SSSR. The photocurrent characterizing the magnitude of the
reflecting power, with the aid of a direct current amplifier, wad recorded on a
POB- 14 loop os iUograRh.\O Simultaneously, in the electrolytic process, measure-
ments were made of the electrode potential, measured with reference to a satur-

ated calomel electrode. A pulse device was used to produce the current pulse;
this made it possible to vary the duration of the impulse over a wide time range.
The electroplating and the anode treatment of the coating were carried out in an
electrolyte of the following composition: CuSO 90 grams/liter; K4P207, 350
41
grams/liter; ammonium nitrate, 20 grams/liter; pH, 8. 1; temperature, 60 C. A
series of experiments was carried out at different current densities to determine
the conditions for anode treatment at which a noticeable increase in the reflecting
power starts. The observed increase in the reflecting power after treatment with
a current pulse beyond the critical point is in all probability connected Nvith the
fact that, at large current densities, a supersaturation of the solution occurs. In
anode dissolving of the metal there should also be observed a smoothing of the
surface of the electrode, i.f the removal of the metal takes place uniformly over
the whole surface of the electrode. It is evident that during the dissolving of
metals, a projection will be completely dissolved if the thickness of the dissolving
layer is commensurate with the thickness of the projections. Therefore, in this
case also, we can expect a smoothing effect. It is possible that both cases occur
during the treatment of copper with a current pulse. Orig. art. has: 7 figures

TOPIC TAGS,* rhentums electrodeposition, passivation
ABSTRACTt The study was devoted to a verification of a proposed mechanism of rhentum
electrodeposition, and to the determination of the passivation rate of the electrode
'Surface. Electrolytes of the following composidons (in g/1) were employed$
(1) ammonium perrhenate 50, sulfuric acid 25; (2) ammonium perrhenate 50j sulfuric
acid 25, ammonium sulfate 40. The electrolysis was conducted at a current density of
1 A/cm2 and 700C for.15 min. In the electrodeposition of rhenium from solution (1)
with an Intermittent current, the minimum on the curve reprosenting the current effi-
ciency of the metal vs. the pause between the current pulsea was found to correspond
to a pause of 10-2 see. As the pause decreases, the current efficiency of the metal
Increases, Indicating that the renewed surface of the cathode does not manage to
become fully passivated. The curve shows that a pause of the order of 1o-3 sec Is
required for the electrode surface to regain Its original state. Thus, the experi-
mental results bear out the "activation" mechanism of rhenium electrodeposition and

show that the current efficiency of the metal depends of the state of the electrode
surf&cep which In turn depends on the admixtures (such as ammonium sulfat,st which is
an activator of the electrode surface) present In the electrolyte. The experiment
shown that In many cases, electrolysis with a pulsating current makes It possible to
determine the passivation rate of an electrode surfoc*. Orig. art. h&&$ 3 figures.

ABSTRACT:' The effect of ultrasound on the electrodeposition of Ni-Fe-Mo alloys from
a sulfate electrolyte containing 2.2-18.0 g/1 sodium molybdate has been investigated
The alloys deposited without ultrasound contained less than 1% molybdenum, regardless
of molybdate concentkation. At concentrations of molybdate higher than 12 g/1, the
deposits were dark and cracked owing to high internal stresses. Ultrasound with
an intensity of 0.9-1.04 W/cm2 and a frequency of 22-26 kc had a beneficial effect
on the electrodeposition process and quality of alloys. At a molybdate concentra-
tion of 8-10 g/1, the Mo content In tie'al]W was 4-5%, the internal stresses in
deposit decreased, and the deposits were dense and lustrous. The optimum pH of
the electrolyte was found to be 2.3-2.7 and the optimum current density, 40-60 a/a~

ABSTRACT: Cathodic polarization experiments were performed in 0.1 N H2SO4 sOlu-
tions, both with and without AS20 .ch was used as a stimulant./~Armco iron and

3OKhGSA steel were used; 3OKhGSA s 1 had the following composition: C (0: %)9
Si (A), Mn (0.9%), P (0.03t), S ( .025%), Cr (0.9%), Ni (0.2%), and Cu (0.2%)..
The quantity of absorbed hydrogen was determined by vacuum extraction at 4000C,
while mechanical properties were measured on samples 3 mm diameter and 20 mm long,
at a strain rate of 8 mm/min. The criterion for determining the amount of hydrogen
embrittlement was the difference A* between the reduction In area for charged and

.uncharged samples. Results are given in terms of A*% as a function of i k (mif/CM2
the polarization current density; and hydrogen concentration as a function Of ik-
:The influence of cathodic polarization of steel on the loss in ductility is severe;
.the curves for A* and absorbed hydrogen content both.pass through a maximum at about
.25 ma/cm2. These same curves were given for cathodic polarization in 0,1 N H2SO4
.solution with 0.01 g/L addition of AS203. A difference is observed; with increase
in ik' the brittleness of the samples and the amount of absorbed hydrogen continu-
,ally increase. An explanation is offered based on reactions at the electrodq:
H + e = H (1) H H (3)
ads ads abs
Hads + Hids H2 (2a)
H + H + H2 (2b)
ads
Thus the concentration CHI ads depends on the speed of disintegration of hydrogen
ions, and on the rate of removal of atoms of hydrogen from the surface of the elec-
trode. The increase in the current density depends on the amount of absorbed hydro-
'gen on the surface of the electrodes, as well as on the speed of its removal; this
removal depends on the recombination mechanism (reaction 2a)-, whose speed is pro-

.portional to the concentration of absorbed hydrogen squared--i = Kl([Hlz )2. The
ads
data are explained using the above considerations, the maxima being as sociated with
a limiting value of hydrogen concentration at the electrode due to the recombina-
tion mechanism. For the As203 additions, there is no maximum because the removal
of the absorbed hydrogen lessened by retarded recombination. Orig. art. has: 4

TITLE0 Distribution of me-l'al on the surface of a cathode
during electrodeposition of nickel
PERIODICAL: Zhurnal prikladnoy khimii, v. 33, no. 12, 1960t
2731 - 2734
TEXT: In order to compare the throwing power of 7 electroplating
solutions (numbered 1, 2, 3 etc. ) used in practice, the distribu-
tion of the nickel deposit obtained from them was examined. Elec-
trolysis was carried out In a cylindrical electroplating tank with
cylindrical anode made from nickel sheet and cylindrical cathode
consisting of Lo metal rings, numbered 1, 29 3, etc., fitted tight-
ly and fixed on one bar. This cathode was placed in tne center of
the tank at an equal distance from the anode and from the bottom
and the surface of the electrolyte. ".3arts of the cathode above
ring No. I and below ring No. 10 were sealed with plexiglassp a

polymethacrylic resin. The distribution of the metal was examined
by determin e increase in weight of each ring after electroly-
SiB. The results are given in which the ratios
Igns increase in weight of given ring ~where 'go?

number of rings
are plotted against the corresponding number of rings. The increase
in weight of metal obtained from each of the 7 nickel electrolytes
is much greater at both ends (ring No. 1 and ring No. 10) than in
the central part (ring Ho. 5 and ring No . 6) of the cylindrical ca-
thode as is expected for electrolytes with poor throwing power. The
increase in weight of the metal on the bottom ring No. 10 obtained
from all the nickel ftlutions is greater than the increase in-,F~
weight of the top ring No. 1. This can be explained by the presence
of convection currents arising in electrolytes from the bottom up-

wards. The 7 nickel electrolytes used in practice could be set in
the following sequency according to the uniformity of nickel de-
posit: electrolyte No. 2, 6, 1, 3, 4, 5, 7. Although for different
nickel solutions many factors such as composition, concentration,
pH, temperature and current density vary considerably, the distri-
bution of metal is nearly the same. These factors have little in-
fluence on the thming power of solution and cannot be changed
without impairing the quality of deposit. The throwing power of
nickel solutions can be improved only by changing the 'geometric
-factors': dimensions form and relative positions of electrodea tak-
ing into account the convection currents in electrolytes as they
influence the throwing power. The table gives the composition of
the electrolytes and the operating conditions. There are 1 table,
2 figures and 11 references: 8 Soviet-bloc and 3 non-Soviet-bloc.

are developed upon their conjugate surfaces, there are pairs
of surfaces with the property of being developable upon another,
whereby the lines of curvature of the one surface change over
into the asymptotic lines of the other surface. The solution
contains four arbitrary constants.

ABSTRACT: Since the reaction under review represents the principal method
for the production of 'crystalline beryllium fluoride, the
course of this process was investigated. The authors mention
in brief the publications available so far on this problem and
especially point out the paper by A. V. Novoselova and M.-Ya.
Averk9va (Ref 14) who first-obtained the ammonium-meta-fluoro-
beryllate NH BeF in addition to'the ammonium-ortho-fluoro-
- 4 . 3
beryllate (NE 4)2 BeF 4* The thermal decomposition of the ortho-
compound in the inert gas current gives only low yields, where-
fore this reaction'was-investigated under decreased pressure.

up'to 165, 180, 205, 220 and 2400 (Pigs 2 and 3) it becomes
evident that the decomposition takou place in three stages:

analysis of (NE 4)2BeF 4' table 2 that of NH4B62F5 . The lattice
constants of NH4Be 2F5were calculated on the basis of a radio-
gram obtained by means of the RKU-86 chamber and found to
belong to the hexagonal syngony (Table 3)- In the same way the
corresponding lattice constants were calculated from the radio-
grams of KBe F (Table 4) and a-CsBe F (Table 5). The radio-
2 5 2 .5
grams are shown in figure 4. Tabie 6 presents the data for the

Periodical : Dok. AN SSSR 98/5, 807-809, Oct 11, 1954
Abstract t The effect of surface-active substances and alternating current on the in-
ternal stresses and porosity of electrolytic coatings was investigated. The
effect of 2,6 - 2,7-naphthalindisulfonic acid and paracresol., on the porosity
of an electrolytic Ni-deposition, is explain6d. The extent to which the
value of internal -stresses is affected by the addition of the above mention-
ed substances is discussed. The parallelism "oetween the effect.of surface-
active substances and variable current on the internal stresses indicates
that the porosity of electrolytic depositions is due mostly to the stresses
in these depositions. Two USSR references (1951 and 1952). Graphs.

Abstract I It was established experimentally that surface active substances added
some times to an acid copper sulfate solution for copper plating
produce different effects on the mechanical properties of the deposit.
It was found that surface active substances can cause internal con-

Periodical t Zhur. fiz khim. 29/1, 185-193v Jan 1955
Abstract I The basic factors resulting in Internal stresses in electrolytic
metal deposit were found to be: changes in lattice parameters, changes
in the distances between the deposition crystals, amalgamation or
enlargemont of deposition drystals and the formation of chemical
compounds between the metal and the admixtures included in it. A
thorough study of the internal stresses of electrolytic metal de-
positions showed a parallelism between the internal stresses origin-
ating in the deposition ard ovarstarain.

Abstract I A nev' method allowing similtameous registration of changes in tha electrode
polarization and luster uccurring directly in the process of electro-
Polishing of metals.. is described. The mechwiism of sroothing during
electrolytic polishine:of silver is explainal. The change in luster of the
electrode surface was found t,~, be closely connected with the speed and
nature of the individual electropolishing processes. The basic facter
aiding the smoothing and consequently increasing the luster of the polished

ABSTRACT: The polarization of the cathode during electrolytic precipi-
tation was studied, and a quantitative study of the different re-
actions taking place on the electrode was made. Data in the
literature concerning the dependence of cathode. polarization on
the cathode cd are contradictory. It is shown"Viat during reduc-
tion of Cr03 reproducible results may be obtaxnkd only with a
constant current intensity I in the circuit or with strictly con-
stant electrode potential F_ , 1) when I = const, the polariza-
tion curve consists of two stable segments wherein the ascend-
ing and descending branches do not coincide; there is a sharply
defined hysteresis loop; 2) when E = const, the polarization
Card 1/2 curve has an anomalous shape; viz., if the polarization of the
137-58-6-12951
Polarization of the Cathode (cont.)
electrode is raised, beginning at a certain value, the intensity of the cur-
rent falls sharply; the ascending and the descending branches then coincide.
It is shown that the reduction of Cr6+ to Cr3+ corresponds to the first seg-
ment of the curve. The rate of this reaction is dependent upon the diffusion
of Cr6+ toward the cathode. On the last segment three reactions take place
simultaneously: separation of 1-42, reduction of Cr 6~ to Cr3+ and reduction
to metallic Cr. Polarization curves for a constant E value in the presence
and in the absence of HZS04 differ sharply from one another. The presence
of HZS04 favors the reduction of Cr6+ to Cr3+ on the first segment of the
curve and shart)ly inhibits the reduction on the second segment. It is shown
that upon an increase of concentration of Fl?SO., the rate of reduction of H
decreases, whereas the rate of reduction of H2CrO4 to Cr increases sharply,
and the rate of incomplete reduction increases steadily. Upon studying the
changes in I with E = const per unit of time it was established that a film
forms on the cathode during electrolysis, which film is destroyed so soon
as the current is switched on.

ABSTRACT: Work on the determination of the relative character of the
distribution of the metal on the cathode in existing Cr batlis is
described. The distribution of the metal was determined by
weighing a cylindrical cathode assembled from 10 metal disks.
It is shown that during electrolytic depositions of Cr a change
in the content of electrolyte does not have any substantial effect
on the uniformity of the distribution of metal on the cathode sur-
face. The best results were obtained in a bath of the following
composition (in g/liter) Cr03 250, HZS04 1.2, H?SiF6 12-

ABSTRACT: The theoretical and exDerimental research into the tempera-
ture field adjoining fric-tion surfaces is said to be still
in a state of uncertainty due to the absence of a reliable
method to measure local temperatures. A variant of the
natural thermocouple method introduced in 1936 by Bowden
and Ridler (Proc. Roy. Scc. A, 1936. Vol 154, D 640) is
proposed. It consists of arranging a steel disc to rotate
whil,zt two specimens, one above the other, are pressed
agai!LSt the cylindzical surface of the disc. The thermo-
electric e.m.f. between the two specimens depends only on
the temperature at the friction surface and the materials
of the two specimens, wh1list -"-h.e d:~ac. acts only as a con-
ductor. In a friction test a variable speed drive
rotates a on a ,.-ertioal shaft pointing downwards.

are mcunted in a block at the end of a swingin.,. arm and
are pressed by a weight, exerting a torque on ~,he axle of
the swinging arm, against the rotating disc. The specimens
are eas-41-y interchangeable, being mounted by clamping in
spe,~Lmen ho--ders inserted in the block. Each specimen
holder fin--,shes with a plunger which compresses a liquid
in a bore into which the plunger fits. The other end
cf the bore is plugEed but the bores of both specimen
holders -ommunii~ata with ea,~h other and a pressure gauge.
Thus the two pressures are equali-sed and measured. The
specimens are -,alibrated against ea~;h other statically.
To obtain the e.m.f. aga.-*Lrst temperature, combinations of
carbon stee-',, bronze, babbit. cast iror, and aluminium were
tested. Figure 4 shows the relation between th'e temperature

Overvoltage During Electrodeposition of Antimony

ABSTRACT: In the present paper the authors investigated polarization
during the electrodeposition of antimony by means of a rapid
method. This made it possible to consider the displacement of
the equilibrium potential and to estimate more precisely the
quantity of the overvoltage. Preliminary results have ohown
that in antimony tartaric acid solutions fine crystalline de-
posits with a current yield of practically 100 % can be obtained.
In figure la a photo of an oscillogram with polarization curves
can be seen which have been plotted by means of the rapid methcj.
The more slowly the curve is plotted the more the equilibriu=
potential of the electrode is displaced in the pojitive directicn.
This is apparently in connection with the fact that a low curzent
density as well as with values i k = 0 an oxidation of the anti-
Card 113 mony surface takes place. Apparently the overvoltage q,-aantity Oru')
