摘要
FIELD: powder metallurgy; reinforcement of wear-resistant tools. SUBSTANCE: method consists in preparation of charge, pressing and sintering in burden; charge is prepared from compounds selected from group consisting of carbides, oxycarbides, carbonitrides and nitrides with addition of steels or alloys containing elements which evaporate in the course of sintering; sintering is performed in vacuum at temperature of 1200-1500 C for 10-300 min; one pressing surface is free from burden. EFFECT: enhanced hardness, strength and wear resistance of material. 1 tbl, 1 ex
