TEXT: The author suggests a method of treat-ng metals with a compressed
gas stream of high temperature to strengthen the surface layer of components, He
investigated the changes in the surface layer of the 40X (40Kh) grade steel und-:-r
the effect of a compressed gas stream (the combustion products of smokeless pois,~4
at a pressure on the surface of up to 600,kg/cm2 and a heating rate of up V~
300,000 degrees/see. Under these conditions, a uniform. white layer of 75#, dept-h
Is formed, in which a martansite-austenite transformation and a carb~,zn &aturat!"r).
of the metal Is taking place which causes an Increaze in the reslst~ux--r- to we-ar,

The white layer on X40 sttel- consisted of martensite; a small quantity
of augtenitt was observed in the surface lgyer 10 mk thick* Initial
&tructure of the steel: Temperature at 500 C after ordinary hardening.
The martensite of the white layer has considerable displacement of the
maximum of the (110)o(, line towards small angles in comparison with its
position for the structure of the ordinary hardening; the doublet
(101 i 011) (110)0~ has no splitting. At the same time the width of
(110)d*, line increaseso For the (111) Y line of the thin surface
layer# a considerable displacement of the maximum towards 4m;All angles
in Alpo characteristice Dato on the (110)0L line are shown on FIX* 2,
Local spectral analysis was made with the result that the carbon con.
centration increases by 0.294 only in the thin surface layer, not in '
other*llayerse The concentration of other elements in the white layer
(Mn and Cr) does not change. Theoretical explanation of experimental
data is attempted* There are 2 figures and 12 referenc*a: 9 Soviet-bloc

TEXT: The purpose of this article is to explain the causes of ero-
sion of the surface layers of a piston ring of an aircraft engine.
The following instruments and devices were used: The apparatus ~t)~;7

X---ay equipment and the installation YPC,-50 (URS-50) for radiome-
tallographyp and the spectrograph KCA-1 (KSA-1 ) for spectrum analy-
sis. Piston rings made of steelo; 38 Y, IN ~OA OMIMA) and Y1 2 M
