METHOD TO PRODUCE HETEROGENEOUS COAT WITH ANTIFRICTION PROPERTIES Russian patent published in 2010 - IPC B23P6/00 B22D19/10 

FIELD: process engineering.

SUBSTANCE: invention relates to recovery and hardening of machine part surfaces using filler materials in electrochemical process to produce wear resistant heterogeneous coat with antifriction properties. Used filler material represents low-carbon and medium-carbon steel wire. Note here that electromechanical upsetting of part surface and welding on are performed in two steps, i.e. first, a groove is produced for low-carbon steel wire to be welded thereto, then another groove is made for medium-carbon steel wire to be welded thereto to produce alternating sections on part surface, hard and not that hard sections.

EFFECT: higher surface quality.
