Abstract

The methods of optical and scanning electron microscopy, micro-X-ray analysis, and analysis of backscattered electron diffraction are used to study the influence of the input energy on the structure and phase composition of coatings obtained by high-energy electron cladding of a mixture of chromium carbide and titanium carbide powders on low-carbon steel in the open air. A correlation between the structural-phase state of coatings and their microhardness is established. The role of titanium carbide particles in the formation of the structure and changes in the microhardness of coatings is discussed.

Keywords:

electron beam cladding microhardness carbides volume fraction of eutectic
