METHOD OF RESTORATION OF WORN SURFACES OF METAL PARTS Russian patent published in 2018 - IPC B23P6/00 B23H9/00 

FIELD: transport machine building.

SUBSTANCE: invention relates to electrophysical and electrochemical treatment, in particular to electroerosive alloying, and can be used for repairing machine parts. Method comprises applying coating with a surface roughness of 1 to 200 mcm to the worn surface of the part by electroerosive alloying with a metal electrode having a discharge energy of 0.036–6.8 J, on which the metal-polymeric material (MPM) is then applied, its polymerization is ensured and it is subjected to finish treatment, while the applied MPM is reinforced before the polymerization with a wire and before it is solidified, the MPM is applied until the reinforcing wire is completely coated with it, while the MPM is initially applied in a thickness at which the level of immersion of the reinforcing wire in the MPM corresponds to at least half the diameter of the reinforcing wire.

EFFECT: invention provides improved adhesion and durability of the part to be restored.
