摘要：
Specimens of steels 30KhGSA, 38KhS and 40Kh, strengthened by plasma hardening, are tested under dry friction conditions in a disk-on-block system. Good wear resistance of hardened steels is established for alloy systems Cr-Mn-Si (30KhGSA) and Cr-Si (38KhS). The wear resistance of single-component system 40Kh is less by a half. This can be explained by the higher carbon equivalent of 30KhGSA steel. Blocks in contact wear to the least with hardened steel 38KHS discs.
