METHOD OF PART SURFACE RECOVERY BY HARD-FACING Russian patent published in 2010 - IPC B23P6/04 B23K9/04 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly to hard-facing recovery of the parts, e.g. solids of revolution, including automotive parts made from alloyed high-carbon steels. Proposed method comprises deposition by consumable electrode on worn-out part surface, the part being moved relative to electrode, producing deposition bath and feeding filler wire insulated from current into said bath. Note here that said filler wire is made from alloyed steel or nonferrous metals and alloys. Wire is fed at acute angle to consumable electrode feed direction ahead or after it in direction of part displacement and at a distance therefrom.

EFFECT: preservation of alloying elements in deposited metal.
