FIELD: metallurgy; mining.SUBSTANCE: invention relates to metallurgy and mining industry, mainly to modification of parts from hard alloys used in mining, and for cold and hot mechanical processing of non-metals, metals and metal alloys, for example, cutting. Method of forming a wear-resistant surface layer in a cobalt-containing hard-alloyed article in the form of a die includes formation of cobalt hydroxide and heterogenites in the surface layer of the die by heating in air at a temperature not less than 100C during 30 minutes.EFFECT: provided is obtaining a wear-resistant surface layer.1 cl, 2 ex |
