SUPERFICIAL THERMAL PROCESSING OF POWDER MATERIALS PRODUCTS WITH LASER HEATING USE ^{[№ 1 ' 2013]}
Influence of laser processing of powder steel plugs on change of microhardness, hardness and intensity of wear process is investigated. Laser heat treatment gives increase in micro-hardness of a surface of powder materials in 2–2,5 time, hardness in 2–2,3 times, and intensity of wear process of a surface decreases in 3–5 times.
