FIELD: metallurgy.
SUBSTANCE: application method of titanium aluminide coating to the metal product contains titanium aluminide cold spraying to the product to form a coating of titanium aluminide. Titanium aluminide coating includes a thin gamma/alpha2 structure, and titanium aluminide, sprayed on the product, it has a composition, including 45 wt % titanium and 50 wt % aluminum. In an embodiment of the claimed invention, the cold spraying of titanium aluminide is carried out from a powder solid raw material of alloy powder.
EFFECT: high resistance to high temperature surface oxidation, products repair, subjected to fatigue failure, having damages from impacts and process damages.
