Abstract

The results of investigation of the phase and elemental composition, defect substructure, mechanical and tribological properties of steel 45, subjected to combined treatment, including plasma alloying (formed by means of electric explosion of aluminum foil) and subsequent pulsed electron-beam treatment are presented. The formation of a high-speed cell crystallization structure in the steel surface layer (cell size 300–500 nm) has been found. The formation of iron aluminides Al5Fe2 along the cell borders has also been revealed. It is shown that combined treatment, including electroexplosive alloying by aluminum and subsequent high-intensity electron-beam treatment, leads to a 2.1-fold increase in the steel microhardness and a 4-fold increase in the steel wear resistance compared to the initial material (steel 45 ferrite– pearlite state).
