Due to the high wear resistance and heat resistance titanium cuprides are used as thermal barrier and protective coatings for copper and copper alloys parts. To reduce the cost and expand the application of coatings, it is proposed to form surface facial layers on copper from titanium cooprides upon argon-arc surfacing using a filler wire of titanium. The results of the formation processes of surfaced alloys based on titanium cooprides are presented. The effect of surfacing modes on the chemical and phase composition of the surfaced metal is established. The effect of the chemical and phase composition on the mechanical and operational properties of the surfaced layers is determined.

The paper offers technology of argon-arc surfacing with titanium wire in order to form heat and wear resistant coating based on the titanium cuprides. The influence of surfacing modes on the chemical compound and structure of formed coatings is determined. The wear resistance and heat resistance at 600°C and 800°C were researched for copper–titanium coating with 8–63% titanium.
