FIELD: various technological processes.
SUBSTANCE: invention relates to a method for electroexplosive sputtering of a wear-resistant composite coating containing an iron-based matrix with inclusions of silicon carbide on an article made from tool steel. Electric explosion of iron foil with weight of 100–400 mg is carried out with silicon carbide powder with weight of 0.5–1.5 of the weight of foil placed on it. Pulsed multiphase plasma jet is formed from explosion products. Surface of said article is fused with the latter at absorbed power density of 2.2–2.5 GW/m2 with deposition of explosion products on the surface of said article to form said wear-resistant composite coating.
EFFECT: obtaining a composite coating with high wear resistance on a tool steel article.
