Micro-Arc Diffusion Impregnation of Steel with Carbon and Carbide-Forming Elements

摘要

The possibility of using micro-arc chemical heat treatment in bituminous coal powder for simultaneous impregnation of a steel surface with carbon and carbide-forming elements, i.e., chromium and molybdenum, is studied. Chemical and phase compositions of the diffusion layers are determined. Formation of carbide coatings based on these elements is confirmed.
