Abstract
The friction wear of surfaces of 40Cr (40Khr) structural steel and 12Cr18Ni10Ti (12Kh18N10T) stainless steel is investigated. It is established, by comparison of the wear of initially annealed 40Cr steel after hardening by radiation from a CO2 laser to various degrees of surface microhardness and separately after volume heat treatment, that the wear is due to fatigue in the entire range of microhardness, regardless of the dispersive properties of the structures. It is shown that the resistance to wear tends to increase with increase of the microhardness of the bearing surfaces. The dependence of the rate of wear on the surface microhardness is obtained. It is found that the wear process is accompanied by formation of a special structurally stressed state in the Saint-Venant region; this state is characterized by a constant hardness level independently of the preceding state of the material.
