Structure, Phase Composition, and Hardness of Coatings Obtained by High-Energy Electron Beam Cladding of a Mixture of Cr3C2 and TiC Powders on Low-Carbon Steel

Resumo

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.
