Surface Alloying of Cylindrical Steel Parts Using Non-Vacuum Electron Beam Treatment

摘要

The technology of formation of high-carbon layers on the pipes of low-carbon steel using non-vacuum electron beam cladding is analyzed. Carbon fiber fabrics are used as a carbon source. High-carbon layers are formed on the surfaces of steel pipes due to the electron beam impact. The carbon concentration in high-carbon layers reaches 5.5 wt.% and decreases toward the base metal. The hardness of the obtained coatings reaches 8 GPa. Cladding of high-carbon layers allows increasing wear resistance of the material by 23% compared to cemented and quenched steel.
