TEXT: Studies of internal stresses in-coatings and paints made
from polymers showed that they were caused by shrinkage taking,
place during drying and hardening.. If'.the properties of the
primer were without.effect on the hardening mechanism, the
characteristics of the primer would have no effect onthe internals
stresses. The latter decreased as the thickness of the,surface
coats, and paints increased. Plasticizers lower considerably-the
modulus of elasticity of the c6ats and cause a reduction of the
limit value of the internal:atresses.

polyethylene ( TU GSNX 10.22-59). The pigments used were chromium oxide
(GOST 2912-58) and lead oxide (GOST .5539-50). Experimental data,
presented in a figure, show that the introduction of 2% total.pigments
into the spraying composition reduces the internal stresses by up to
50%- Further addition of pigment has less effect; chromium.oxide has a
greater effect than lead oxide, The article gives a formula-for
Idetermining the internal thermal stresses in the costing as a function.
of tbd coefficients of linear expansion of the costing and the supporte.
Other properties investigated were the changes in the strengtbp the
adhesion, and the permeability as e.result of the addition of pigments.
~Introduction of 1-2% total'cbromium oxide into the coating increases the
,strength by 17-0%; lead oxide has practically no effect. Large amounts
~of pigments lead to a gradual decrease in the strength. Addition of
~1-4% total pigments increases.the adhesion of tbacoating, Larger
amounts lower the adhesion. Introduction of up to 2% totalebromium

10
place in the form of H (0-1 - 0-5 9/1) in order to keep the experi-

effect of 80 as a function of PH and current density was also examined.

The results: 1) at PH > 6.0, So 2 does not exist in the free state and
therefore has no effect upon electrolysis. 2) At PH =- 4 69 so2 has an
effect upon the chemical reaction in the solution. The current output on
manganese is increased and the formation of dendrites on the cathode is
reduced- 3) At PH -/, 4-0, S02 takes part in the reactions on the electrode.
The cathode polarization increases, the precipitates contain sulfur (0.1

TEXT: The effect of cathade-reduced hydrogen upon the mechanical-
properties of metals is studied'.,For this purpose,'the effect produced by
-cathodic polarization upon rolled iron, rolled nickel and blectrodepositeU
nickel is studied. The cathodic polarization was carried out in a 10%
sulfuric acid with an addition of 0.1 gli Na2S, current density 100-ma/dm2,
temperature 20 - 250C. The following measurements were made: 1) Measurement
of the diffusion of H2 into.the metal; 2) Measurement of -the deformation
of unilaterally polarized lamellas due to H2 adsorption; 3) Determination
of the adsorbed H2 by means of extraction in vacuum; 4) X-ray analysisj
5) Determination of the strength before and after cathodic polarization'

Effect of Cathode-reduced Hydrogen on the S/02Y61/136/003/023/027
Properties of Metals B004 B056
The following results are enumerated. A) Rolled nickel: Hydrogen diffuses
only to a depth of 304; causing internal stress of the magnitude of-
10 kg/mm2. Brittleness ,occurs, and strength is decreased. This brittlendss
disappears after 60 - 70.hours,of keeping the specimen in air. During this
timethe entire occluded hydrogen ia.eliminated. The strength increases
as compared to the initial value by 5-6%. B) Electrodeposited nickel:*
Hydrogen diffuses deeper into the metal than in the case of rolled nickel,
and in polished surfaces more.quickly than in dim ones. Apart from the
fact that in electrodeposited nickel cracks easily occur due to occluded
hydrogen, the behavior is analogous to A.). C) Rolled irons: Hydrogen
penetrates very deep into the metal. Internal stress of about 15.k#/mm2,
increased brittleness, and local destruction occur. The major-quantity
of occluded hydrogen is eliminated completely only after 6 - 7 days, the
strength, however, remains irreversible (15-20%), and flexibility is
reduced by 50%. A change in the lattice parameters was, however, not
observed. The following conclusions are drawn: The H2 penetrated into the
metal collected in the microcavities of structural defects and thereby-
causes internal stress. Part of the H2 is adsorbed on the surface of the

defects, reduces the surface energy and thus also thestrength of the
metal. While in the diffusion of H2 into Ni the effect of the adsorptive
reduction of strength predominates, in the diffusion Of H2 into Fe that of
the effect of the internal stress predominates. Experiments showed that
accelerated extraction of hydrogen in the vacuum also eliminated
brittleness. This proyes the.connection between brittleness a 'nd hydrogen
content. There are 4 figures and 5 references: 4 Soviet and 1 Polish.

ABSTRACT.- The author analyzes the motion of a holonomous system of N material,
points, of.which e points have constant mass, k points vary their
mass due to emission of partiales,and r points vary the'ir,mass due
to simultaneous emission and aceretiori of particles.. The.motion
equations are'obtained in holonomous coordinates, which represent
a generalization of the Boltzmann-Hamel equations. These equations
are found for the cases when the variable masses are functions of:
a) time only, b) generalized coordinat 'es only, :a) generalized
velocities only, d) time and generalized velocities.

"ABSTRACT.- The hypersonic TioK of an ideal ggs over%a c1rq1kw cone-is considered
at an angle of attack. A method of successive approximations iB outlined which
would permit finding a uniform approximation to the exact solution in the region,
between the shock wave and the cone, including the vortical layer. The fundamental
concept of the method consists of introducing a special system of coordinates for
the entr yOpquation which with the removal of a logarithmic singularity becomes
possible. This is obtained by using the method of'small parameters. A solution in
obtained with accuracy up to and including the second order. Comparison is made
with the -results of Chang's work and the author's previous-work (Chang,, H. X..,
