SUPERFICIAL THERMAL PROCESSING OF PRODUCTS FROM POWDER MATERIALS WITH USE OF LASER HEATING
Influence of laser processing of plugs from powder steels 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.
