ABSTRACT: The effect of the decrease of optical density for the investigation
of the temporal dependence of the H902 separation by metals after pu-
rification, as well as for the comparison with the data obtained vrith
the investigation of the kinetics of corrosion according to the weight
method was applied here. The tests shoaed that the amount of this
effect depends on the exposure time of the preceding exposure. For
investigating this dependence, strips parallel to each other of one
and the same photographic plate at constant illumination were exposed
during various times. Subsequently, a newly cleaned zinc rod was
fixed on the photographic layer vertical to these strips. The optical
densities Di (there, vihere the metal ;-ias) , and D (of the remaining
part of the plate) were measured for each strip after developing and
the L D, the decrease of optical density, was computed. The invest-
igations showed the same course of the curves for the action of metal
and F202. This proves that the effect of a decrease in optical density

the intervals from 1 up to io days. These curves plotted photograph-
ically coincide -,ath those for the increase of the thickness of the
layer of oxide, ahich were obtained by Vernon Refs.6-7 according to
the weight method. It is shown that various equations which express
the dependence aith respect to time of the separated quantity of hy-
drogen peroxide, or of the thickness of the layer of oxide respectiv-
ely, correspond to the various stages of metal oxidation. The tests
were carried out at 200 C and a relative humidity of from 65 to 7~rlb.
From the obtained data results that a -oarabolic relation of the form
n2=k~t+k 4 exists -~rith an interval of f-rcin I to 2J+ hours from the be-
ginning of oxidation. The analogous tests within the interval of from
I to 10 days showed a logarithmic course of the dependence of the
form: n=k5 lg t + k6. There are 7 figures, and 7 references, 4 of
which are Slavic.

The effect of relative humidity A057/AI29
in corrosion was observed after attaining fferitical humidity". This increase was
explained by the formation of an electrolyte film on the surface, effecting a
change from pure chemical to electrochemical corrosion. In prior investigations
(Ref. 7s DAN SSSR, go, 603, 1953; Ref. 8: DAN SSSR,"94, 1117, 1954; Ref. 9: DAN
SSSR, 108, 110,_;', 1954; Ref. 10: ZhM, 31, 2733, 1957) the present authors ob-
served the photographic effect of metals caused by the evolution of H202 during
corrosion. Subsequent experiments showed a linear function between the growth
of the oxide film and the amount of H202 formed in atmospheric corrosion of mag-
nesium and aluminum. Thus corrosion can be controlled by estimating the H202
evolution process. This was the principle of the present investigation. Spec-
trally pure aluminum (Si 0.0016 %, Fe o.oo16 %, Cu 0.001 %) and magnesium (Fe
oxo4 %, si mog %, M 0.0021 %) were used in the experiments and no agressive
media were introduced. The photographs were made with Isochromatic reproduction
supercontrast photoplates (sensitivity 1.4 FOCT' (GOST)). Blackening increased
by preparing the plates successively with 4 % Na2C03 solution (4 minutes) and
50 % ethanol (1 minute) with subsequent drying (10 minutes) at 1000C. Constant
humidity'P was secured by placing a NaOH solution of a corresponding concentra-
tion (%a0H ' 48, 41, 33, 27, 13 % corresponds to 15, 30, 45, 6o, 75, 90 %)

on the bottom of the cylindrical hermetically closed glass box, where the experi-
ments were carried out. After exposure to the H202 evolved by the sample at a
certain humidity in the test box, the photoplates were developed and the optical
density D- of the blackening was determined. The dependence of the optical den-
sity D of the photoplate blackening after exposure to a solution of H202 of a
certain concentration at a certain humidity -" was determined and corresponding
curves were plotted. From these curves and values obtained with metals the depen-
dence of the evolved H202 amount p on', was estimated (Figure 4). The observed
increase in p with ~N is In agreement with literature 'data (Ref. 1,2,4) indicating
an increase in the oxide film with increasing -' . In the present investigations
also the amount p of H202 evolved from the metals during corrosion at varying
was determined and the results are shown In Figure 5, demonstrating that for(P
0 - 90 %, log p = a ~! + b (where a and b are different for the interval 0 - 30 %
and for 30 - 90 %). These results are in agreement with data given by N., D.
Tomashov and A. A. Lokotilov (Ref. 15: Sb. "Korroziya I zashchita staley" ("Cor-
rosion and protection of steell Pladigizdat 158, 1959). Kinetics of HpOp evolution
were studied during the first 6 hours of corrosion for - = 0, 15, 30, 45 and 6o
The amount of H202 formed during the first 15 minutes was considered as unit in
these experiments. The obtained results plotted in squares of the formed H202
