FIELD: metallurgy.
SUBSTANCE: surfacing is performed on the flux layer with wire from aluminium or its alloys. Flux containing chrome oxide and cryolite is used with the following component ratio, wt %: chrome oxide (III) 25-35, cryolite 65-75. Surfacing is performed in shielding gases in the modes allowing to obtain the coating containing 10-40 wt % of aluminium.
EFFECT: formation of surfaced layer on the basis of intermetallic compounds of aluminuim FeAl and Fe3Al alloyed with chrome provides the increase in wear resistance of working surfaces of the parts.
