摘要：
Special features of structural transformations in steel 40Kh under friction observed in an operando experiment are studied using diffraction of synchrotron radiation. Variation of the chemical inhomogeneity of martensite under friction loading is determined and the effect of this phenomenon on defects of the crystal lattice of martensite is analyzed. It is shown that the interaction in the “alloy VK20 – steel 40Kh” pair under the specified conditions causes oxidation of the iron-carbon alloy and thus contributes into occurrence of steady friction wear.
