摘要

FIELD: process engineering.;SUBSTANCE: invention may be used for surfacing parts subjected to active intensive wear effects at higher temperatures and multiple temperature differences, for example, hot rolling rolls, etc. electrode outer surface is made of steel or nonferrous metal. Powder filler comprises components in the following ratio, in wt %: tungsten carbide, at least - 50, cobalt - 6-10, nickel - 3-4, titanium carbide - 5-7, copper - 0.25-0.5, iron powder - 10-20, fluorite - 5-10, rutile concentrate - 4-7. To make antiwear layer on foundry equipment surface is performed by depositing aforesaid composition by electrode at the rate of 100-150 m/h at current density of 200-450 A/mm to antiwear layer thickness of 1-12 mm.;EFFECT: longer life at operation at 750 to 1150°C.;5 cl, 1 tbl, 7 ex
