METHOD OF INTERMETALLID ALLOYS FACING ON THE BASIS OF THE TITAN-COPPER SYSTEM Russian patent published in 2018 - IPC B23K9/04 B23K103/18 

FIELD: technological processes.

SUBSTANCE: invention can be used in the application of heat-resistant and wear-resistant layers to parts made of titanium or titanium alloys operating at elevated temperatures under abrasive wear. Electric arc facing is carried out by a non-consumable electrode in an environment of inert protective gases using a filler wire made of copper or copper alloys. Facing is carried out on the regimes ensuring the formation of a weld layer with a copper content of 5–40 %. This content of copper during surfacing provides the formation of a weld metal structure based on a supersaturated solution of copper in titanium and an intermetallic phase Ti₂Cu, that contribute to an increase in wear resistance and heat resistance of the working surfaces of parts made of titanium and titanium alloys.

EFFECT: technical result of the invention is an increase in the operational properties of the deposited layers.
