TITLE: On the Initial Quantity o~- Dust in Working With Models o1
Dust Collectors
PERIODICAL: Zavodskaya laboratoriya, 1959, Vol 25, Nr 10, pp 1258-1219

ABSTRACT: For the purpose of investigating a separation of aerosols
in models of various dust-collecting devices a simple and
reliable method was worked out, in which the dust-collecting
surface is coated with a viscous liquid (e.g. vaseline), The
quantity of dust deposited on this surface may be determined
according to various pnysico-chemical methods (Ref 1). As
the minimum size of the dust particles absorbed by a device
is determined by the dimension of the latter, experiments
must be carried out with the finest particles in order to
attain greater efficiency of the device. Several experimen*
(Ref 2) showed that greater quantities of fine dust may
absorbed on a viscous surface than was stated in a paper LY
N. F. Dergachev (Ref 1). In order to solve this problem
experiments were carried out with a model with a tube havin,

quantities of a fine (0-12 p) dust of K,Cr207 at a tan~;en-
tial air flow velocity of' 7 m perBexnd, It was found that
a variation of the quantitief~ of dust from 9.6 to 205 mF
(Fig, diagram) influences neither the total degree of sei_,ar;,-
tion nor the distribution of the deposited particles along
the model. Thus, when working with fine dust (0-12 p), the
initial quantity may be much higher than previously stated.

ABSTRACT: Methods were described for investigating the corrosion (C) of
metals in narrow gaps (G) which make it possible to study the
corrosion behavior of metals in G of various magnitude and in
the case of arbitrar-j ratios of the surfaces of metal in G and
in the electrolyte mass. Electrolyte of 0.03 g/1 NaCl + 0,07 &/1
N SO was taken as initial medium, to which various corrosion
iNMtors (CI) were added. The test results have shown that the
C rate of Fe in narrow G is lower than the C rate of Fe surrounde-;
by the mass of the electrolyte. This Is explained by the lnhiblt!~'i.
of the cathode process as a result of the difficult access of 02.

and in G of 0.05 - 0.35 mm it has approximately the constant va-lue of 2.0 -/.-m2
In the presence of a contact with the metal in the mass of the electrolyte, the
C rate of Fe in G does not change with the G width. This is explained by the
fact that the couples of differential aeration "metal in G-metal in the mass"
are little efficient due to the high resistance of the medium. In the presenre
of CI it was established that NaN02, K2Cr 207, Na2HP04 cause a strong local C of
the metal in G, although in the mass even small additions of these C1 suppress
the corrosion process completely. An increase in the NaN02 concentration leads
to the reduction of the corrosion damages of Fe in G and :in the caze of a
concentration of 2.0 9/1 NaN02 C in G can be completely suppressed. The same
results are observed in the case of K Cr 201and Na2HPO 4. ZnSO does not cause
C but is little effective. A temperXre ncrease affects C 0~ Fe in G in a
double way: 1) at raised temperatures a higher concentration of CI is needed;
2) with the temperature increase the rate of CI diffusion into G rises (the
first factor prevails). The whole anode current in a metal in G of 0.05-0.31, aur
is concentrated on the surface of the sample located not deeper than 5 mm from

of other oxidation means. Under normal conditions in 0,5 r
NaCl they are in an active state. So far as these steels
corrode with the depolarization of oxyEen their corrosion
velocity in the electrolyte is hiEher than that in the
slit where the ap --iroach of oxyEen is rendered more difficult.
High-alloyed steels (13 ~fo of chromium and above) in the
electrolyte are as a rule in a passive state. ~ihen these
steels, however are in a narrow slit where the anproach of
oxygen to the metal surface is incomparably more lifficult
than in the electrolyte there is a much Ireater probability
for a discontinuation of the passive state of steels and
therefore also for the formation of destructions b3 corrosion.
The authors eslablished that with steels with 13-17/o of
chromium the passive state in slits is interrupted ~:Lnd
pittings are formed. In the presence of a contact -i,-ath the
steel washed around by an cl!ctrolyte the corrosion of the
steel in the slit int-insifies at the expense of the formation
of active-passive elements, Some cons derations on the
-,rocess of a destruction by corrosion are Liven. If the

steel has a chromium content which is not sufficient to
shift it to passive state in C,5 N NaCl the corrosion of the
metal in the sl1t takes place as described in ref. 14.
Consequent to an abrupt slowing-down of the cathode
process the velocity of corrosion of such a steel will be
slower than in the electrolyte. The operation of differential
ventilation is little effective under these circumstances.
If the steel, however, has such a chromium content that it is
shifted in the electrolyte to a passive.state this steel is
exposed to an increased destruction in a slit. The
destruction takes place because of the fact that the entrance
of oxygen to the slit is rendered more difficult wid there-
fore the passive state of the steel in the slit is very
unstable and may be disturbed at some pldces of the metal
surface. The investigations showed that the steel is initially
in a passive state and only aftur a certain time, which
depends on the chromium content, passes over to an active
state: the less chromium there is in the steel the earlier
the passive state in the slit is disturbed. In fine slits
Card 3/4 the passive state can be disturbed on almost the whole

surface in the slit. Yith jreater slits this applies only
to a limited extent.

of bronze, whereas brass reacts in a different way. In crev-1ces
(0-5 mm and below) of' brass the corrosion is stronger in the
crevices and may reach a twentyfold value, especirilly on
contact with the outer surface (Yie 4). In this case the brass
crevice acts as anode. The anodic polarization as well as the
corrosion of brass lead to a selective dissolution with zinc
being favorably dissolved. The strong zinc reduction in brass
crevices can be explained by a more difficult oxygen access as
has been found by tests in a hydrogen atmosphere ( Table 2),

TITLE: Mechanism of the corrosive destruction of iron along the
water line
PERIODICAL: Zhurnal fizicheskoy khimii, v. 35, no- 1, 1961, 206-211
TEXT: The authoro were conoorned with the problem of the intensive
corrosion of low-alloy steels along the water line, i.e., along the line
separating the corroding medium from the atmosphere. According to
I. L. Rozenfelld and K. A. Zhigalova (Ref. 1) the process has a different
course depending on whether the electrolyte surface remains immobile, or
whether its level fluctuates. The corrosion of Armco iron was examined in
various media with the surface at rest. The formation of differential
aeration couples was observed. Fig. 1 shows the element "metal in water
line - metal dipped in electrolyte". The following results were obtained:
An intensive corrosion appeared along the water line in acid media and in
neutral solutions containing inhibitors such as bichromates, nitrates, or
phosphates. The iron dl.d not undergo any intensive corrosion along the

water line in neutral chlorides and sulfates. An intensive local
destruction may take place, however, in media with a low electrical con-
luctivity. Due to the difference in access of oxygen to the iron of the
Water line and iron dipped into the electrolyte, differei,tial aeration
couples are formed, the anode being provided by the iron dipped into the
electrolyte. In media with a low electrical conductivity (tap water) the
currents of these elements concentrate and give rise to intensified
corrosion somewhat below the water line. The intensive etching of iron
along the water line in acid media is not, as hitherto assumed, caused by
a stronger precipitation of the corrosion products at the water - air
interface, but by the action of corrosion macrocells, whose anode is the
Fe in the water line. The cause of the formation of such cells is the
rapid increase of the pH of the electrolyte which forms the meniscus. In
neutral electrolytes containing inhibitors, the corrosion of Fe is similar
to that in narrow slits and crevices. Due to an impeded access of the
inhibitor to the electrolyte forming the meniscus there arise active -
passive cells, which give rise to the intensive corrosion. There are 4
figures, I table, and 9 references: 6 Soviet-bloc and 2 non-Soviet-bloc.

TITLE: Mechanism of selective linear corrosion
PERIODICAL: Zhurnal fizicheskoy khimii, v. '5, no. 6, 1961, 1265-1269
TEXT: The object of the present paper was a study of corrosion at the
boundary metal -dielectric. The authors used Armco iron, and showed its
corrosion in the presence of HCI or H 2so 4' Corrosion was mcst distinct
in 0.2N R2so 4' Besides paraffin, the followiig substances were used as
dielectrics: colophony, bitumen, organic glass, polystyrene, polymerizei
0-2 (BF-2) glue, and Bakelite varnish (Fig. 1), No effect of the
character of the dielectric on corrosivn was observed. Linear corrosion
was also observed at the contact point of tAo homogeneous metals. Weak
corrosion was even observed with electrolytes free from 0 2* The jepth of
corrosion increases with the metal surface outside of the paraffin drop
Thus, the free metal parts exert an influence on the covered parts. In

the narrow interspace at the edge of the drop, the acid concentration Js
reduced due to interaction with the metal The increase in pH leads tD
a derefinement of the steaJy metal potentiRl and to an arceleration of t-;e
anodic metal ionization, The change in acid concentration on the var-Dus
metal Darts leads io the formation of concentration elements. The anodi,
processes took place at t~~e narrow edge on the drop, the cathodic proce5ses
at a greater distance, on the metal. At sufficiently high H+ concentra-
tion, free H2 is formed by discharge. This produces a cathodic process
zausing corrosion in the absence of 0 2' A clear demonstration is 4ziven
by the following arrangement: Two Fe electrodes are taken, one of Ahi-h
forms a 0.3 mm wide margin between metal and polymer An emf of B'U-10C:Lv
and 500 pa is formed. The metal in the slit acts as anode. The -,H
dependence is Jillustrated by the following arrangement: Two Fe electrodes
are put in an H-shaped vessel with glass diaphragm. A milliammeter ds
connected.. Both wings are filled with 0.2 NH 2so 4' In one wine, the acid
is titrated with 1N NaOH +0.2N Na 2so 4' In the other one, the same
quantity of acid %as added to prevent a flow of the electrolyte through

tion of metallic copper and MgCU2 in case of Mg Cu. The fomation of intermediate
ntermetallic compounds which are rich in the able component may also be observed
r
~during dissolution of In2Bi. Phase transitions with the formation of the noble com-
nent take place when M92Sn and Mg3Sb2 are treated in hydrochloric acid, with the
itmony passing into solution in quantities of 8-10% while the tin concentration in
solution is only slightly less than its content in the alloy. The experimental data

ABSTW~CT: The object of the work was a systematic study of the corrosion 'And alectro-
chemical properties of magnesiu-ni-antiniony alloys and thoir relationship to tho phaso
diagram. The system contains the intermetallic compound Mg3%, a sOmJ.cOnductor. T~c
composition and structure of the alloys (which all exhibited a p-type condlictivi'-Y)
were checked by cherdeal and mota-1lographac analysis. The corrosion behavior was
studied In 0.5 N 14C1, 0-5 N NaBr and 0.1 N' HGI at room to:"rature. Tho cor-os'lon
rate was found to increase with decr,)asirq-, p1l. In alloys colltailling Up to 7""'b' Sb, it
is determined by the work of "1 11 5b ~-aso mic.-oc.)Ils whose electrodes havo a con-

CHEMICAL BOND IN SEMICONDUCTING COMPOUNDS OF Zn AND Sb (USSR)

Short-range interatomic order in the semiconducting compounds Zn3Sb2, ZnSb,
and Zn4Sb3 has been studied by x-ray spectroscopy at the Vcronezh State Uni-
versity. The Kai and Ka 2, lines of Zn in all three compounds were observed
to shifi toward the short -wavelength region as compared with the same lines in
Zn metal. The shift, which increased in the order Zn3Sb2 f ZnSb < Zn4Sb 3, is
attributed partly to an assymetric distribution of density in the electron cloud.
This distribution is responsible for a decrease in the shielding effect of the
'valence electrons and, thus, for an increase in the effective charge of the
cationic nucleus. The shift is ascribed in part also to the difference in valency
of the cationic element in each compound. The shift of the Kaj and Ka 2 lines
per unit of "formal" valency, that is, the ratio of the total number of valence

electrons in Sb to the number of Zn atoms in the compound, was shown to in-
crease in the order ZnSb 'C Zn3Sb2'~ Zn4Sb .. The contribution of the ionic bond
increases in the same order and is correlated with the semiconducting proper-
ties of the cc,:-.%~:,ounds. The same correlation exists in the series CdSb, Cd3Sb2,
and Cd4Sb3; that is, the widths of the forbidden zone in these semiconductors in-
crease in the same order as the ionic-bond contribution. JJK )
