FIELD: metallurgy.
SUBSTANCE: wear-proof coating is deposited on aluminium alloy. Mid ply is formed in said coating. Then, chromium carbide ply is applied thereon by vapour plating of bisarenchromorganic compound. Note here that said mid ply is formed from nickel-cobalt alloy by electrochemical process.
EFFECT: coating continuity and strength of adhesion to the substrate from aluminium alloy with high content of silicon, lower time, power and labour input.
