Electron-Beam Cladding of Boron Carbide on Low-Alloyed Steel at the Air Atmosphere

Article Preview

Abstract:

An investigation of coatings obtained by cladding of boron carbide on a low-alloyed steel substrate by an electron beam injected into the air atmosphere was carried out. It was shown that hardened layers had a heterogeneous structure formed during rapid cooling. It was established that a volume fraction of iron borides in the surface layer had a considerable impact on mechanical properties of the material studied.
