TITLE Polarization of the Cathode During the Ele(ti-olytic Deposition
of Chromium (Polyarizatsiya katoda pri elektroosazlidenii

PERIODICAL V sb.' Teoriya i praktika elektrolit. khromirovaniya. Mos-

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 that during reduc-
tion of Cr03 reproducible results may be obtafni4d 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

11;7-58-6-1295i
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 CrO 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 H2, reduction of Cr6+ 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 prc_~ence
of H2SO4 favors the reduction of Cr6+ to Cr3+ on the first segment of the
curve and sharply inhibits the reduction on the second segment. It is shown
that upon an increase of concentration of H2S04 the rate of reduction of H+
decreases, whereas the rate of reduction of H?Cr04 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: An investi,iation was carried out with the object of verifying
the mechanism of Lhe discharge of the Cr6~ ion durin its re-
duction to metallic Cr. Use of the tagged atom of Cr5q af-
forded a means for the determination that the reduction of
chromic acid to Cr takes place directly without formation of an

TITLE: Effect of film composition on alloy formation during electro-
deposition of chromium together with other elements
PERIODICALs Zhurnal fizicheskoy khimii, v. 35, no. 3, 1961, 647-650
TEM The effect of film composition on the electrodeposition of chromium
together with other elements was studied. It was established that the de -
position of metallic chromium depends on the nomposition of the film andnot
on the composition of the electrolyte solution. Investigation of the cathodic
polarization In an electrolyte consisting of 2.5 moles/1 of CrO 3 and 0.025
mole/1 of selenic acid on a gold cathode showed that, in principle, the ef-
fect of selenic acid on the electroreduction of chromic acid is the same as
that of sulfuric acid. An alloy of chromium with selenium forms on the
cathode during this process. This alloy also forms when adding f3elenious
acid instead of selenic acid. The reduction rate of the chromium ions is af-
fected,not by the ion concentration in the electrolyte, but by the ion con-
centration in the film. The change of the composition of the Cr-Se alloy
Card 1/3

s/076/6i/o35/'oo3/oia/023
Effect of filyn B121/B206
on a change of tile concentration of selenic acid in a 2.5 M chromic-acid
solution at a current density of 0.50 a/cm2 and a temperature of 200C was
also investigated on platinum electrodes, The results showed that tile
p.jrcentage of selenium in the alloy rises to 0-15 mole/l witb an increase of
tie selenium concentration in the solution. The compcsition of the Cr-Se
allot'remaino unchanged with a further Increase of the ,ielenjum ooncentration.
The same rule was also established for a replacement of selenic; acid by
selenious acid. During electroreduction the permanganate ion has no reduc-
ing effect on chromic acid. The ability of forming a film on the cathode
thus depends first of all on the nature of the anions. The effect of the
sulfuric-acid concentration on the percentage of selenium in the Cr-Se alloy
during deposition from a solution with 2.5 moles/1 of chromic acid and
0.1 mole/l of selenic acid was studied, and it was established that the
selenium content in the electrolytic depovit decreases with increasing
8ulfuric-acid concentration. Partial exchange of sulfuric acid for selenic
acid in the film results in a decraase of the reduction rate of the selenium
ions. There are 3 figures and 5 references: 4 Soviet-bloc and 1 non-

PERIODICALs Zhurnal fizicheskoy khimii, v- 35, no. 9, 196-1, 2142-2143
TEXTt According to D. N. Usaohev and A. T. Vagramyan (Ref.2t Zh.fiz.
khimii L2p 1900P 1958), the reduction of chromate ions to metallic chromium
is effected by products originating from a special cathode film containing
anionic reducing agentst and not by ions present in the solution. A con-
dition indispensable for the simultaneous depositi,in of chromium and other
metals is the presence of an anionic coprecipitated substance in the
ohromic-aoid electrolyte, which was experimentally proved bY th deposition
of Cr-Nn and C'r-Se alloys effected by introducing Mno- and SeO2'! ions.

The anions [AuCl4)- and were not reduc 'ed eleotroly.tically under
the conditions given. It follows that the simultaneous presence of various
anions is not a sufficient condition for their simultaneous reduction with

chromate. The reduction of anions in chromic-aoid solution takes place
in two stepst 1) penetration of anions into the film, and 2) their reduction
in the film. The penetration of anions into the cathode film is investi-
gated by using anions which do not'affect, the eldotrolysis of chromic acid,
are not subject to electrolytic decompgaition, and are called neutral
anions. Th 'esb neutral anions may'displace either chromate ions or chromate
and foreign anions simultaneously, or only foreign anions on -penetration
into the cathode film. If neutral anions are capable of penetrating into
the cathode film which forms during electrolysis of chromic adid in the
presence of an amount of sulfuric acid corresponding to the maximum current
yield of chromium, the current yield of metallic chromium will decreasel
otherwi.se, it will be constant. Based on data given in Ref-3(E- Liebreich,
Z, Elektroohem. 46, 73, 19341 E- Ydller, )Lreh. Metallkunde 2, 110# 1948)0
the h 1. h to ion may be consid!red a neutral anion. The c~opounds

the dependence of the current ;,nsity on the cathode potential in the
presence and absence of sulfur '3 acid was investigated. The polarization
curves wore obtained on the at-,imium cathode using a potentiostatic method;

current density of 0.2 a/cm 2 (Pig.), the current yield of metallic chromium
decreases with increasing concentration of neutral anions.
Hence, it can
be concluded that all anions investigated are capable of penetrating into
.,the film together with the chromate and sulfate anions.' The capability of
Aons of penetrating into the cathode film is determined by the negative
sign of the ions, and is independent of their nature. There are I figure

with fast neutrons. At first the active zone of the reactor Is dis-
cussed. The heat-separating elements of che reactor BP-2 consist of
plutonium rod5 of lo mm diameter and 130 mm length. Besides the plu-
tonium rods there are similarly constructed rods in the active zo-
ne which are made of poor uranium. Altogether there are lo3 u-
ranium- and plutonium rods which are mounted in a steel tube with
an inner diameter of 130 um. The reflector of the reactor consists
of an uranium layer (outer diameter 700 mm) and a copper layer
(outer dia.-jLer looo mm). The reactor Is controlled by a control
system and by an emergency system. The operating control organs are
part of a screen which are located near the active zone. The con-
trol system also contains boron-ionization chambers, an electronic
apparatus, and servofeeds. The emergency system enters into operat-
ion if the prescribed or assumed power of the reactor is exceeded.
Circulating mercury is used for the system of heat conduction. This
mercury is then cooled in a heat exchanger with water. The radiat-
ion protection of the reactor consists of the following parts:

TEXTs Attempts are made to determine sufficiently exact neutron distribu-
tions at various distances from the source, including distances shorter .
than the mean free path. In order to eliminate the -1 6V-1) singularity,
r2
all neutrons that have,not suffered even one collision are singled out, so
that the source consists of neutrons that collided once. The problem is
treated in a similar way to the isotropic case. The eingularities in the
neutron distribution after the first collision are treated separately from
those after the second since the distribution function T(r,n) is assumed to
be the sum of the functions representing these aingularities (subscripts
1,2) and a smooth function (subscript ri)) not containing them. The authors
