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.
