FIELD: metallurgy.
SUBSTANCE: powder composition mixture for laser build-up on the metal base includes powders of titanium and silicone carbide with particles size 20-100 mcm at the following ratio of components, parts by weight: titanium - 5-7; silicon carbide - 3-6. Titanium powder particles can be in form of spheres.
EFFECT: assurance of uniform distribution of hard inclusions over volume of coating due to synthesis of the titanium carbide, resulting in improvement of the coating quality, namely its hardness and wear resistance.
