METHOD OF FACING OF TITANIUM AND TITANIUM ALLOYS OF HEAT-RESISTANT AND WEAR-RESISTANT COATINGS BASED ON TITANIUM ALUMINIDES Russian patent published in 2019 - IPC B23K9/04 B23K103/18 

Abstract RU 2699474 C1

FIELD: technological processes.

SUBSTANCE: invention can be used in application of heat-resistant and wear-resistant layers on parts from titanium or titanium alloys operating at high temperatures and in conditions of abrasive wear. Electric arc surfacing is performed by nonconsumable electrode in medium of inert protective gases with application of aluminum filler wire at modes ensuring production of welded layer with aluminum content at level of 5–25 %.

EFFECT: said aluminum content during surfacing provides formation of structure of weld metal on the basis of supersaturated solution of aluminum in titanium and intermetallic phase Ti3Al, which improve wear resistance and heat resistance of working surfaces of parts from titanium and titanium alloys.
