FIELD: process engineering.
SUBSTANCE: invention may be used in applying coats of titanium alloys on parts operated in friction, impact loads etc. Wear resistant coat is applied using consumable electrode in atmosphere of protective gas. Welding wire from titanium alloys is used as consumable electrode without whatever extra processing. Built-up hardness results from doping built-up metal by oxygen added to protective inert gas. Oxygen content in gas mix makes up to 20%. Said oxygen content allows built-up metal hardness approximating to 5400 MPa.
EFFECT: higher hardness of built-up metal, lower costs.
