METHOD OF PRODUCING ARTICLE FROM MULTILAYER SOLID ALLOY BASED ON TUNGSTEN CARBIDE

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to powder metallurgy, particularly to production on multilayer articles from tungsten carbide-bases solid alloy. Graphite interlayer is formed on the surface of article made from high-cobalt solid alloy and one layer of low-cobalt solid alloy or two layers of low-cobalt solid alloy are applied thereon by electroerosion to produce graphite interlayer there between. ^ EFFECT: higher surface hardness, wear resistance and durability. ^ 1 ex
