FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of antifriction sheet materials on metal substrate. It may be used for producing antifriction bearings operated both lubed and dry, at higher sliding speeds, loads and temperatures. Porous cermet layer is produced on substrate from iron-nickel alloy by sintering a mix of fine disperse powders of copper and alloy to said substrate by pressing there said mix against said substrate by stainless steel gauze at 810-820°C. After sintering, said gauze is removed to produce sintered porous layer of reticular structure. Content of said powders in said mix makes in wt %: copper - 84-86, tin - 14-16.
EFFECT: higher wear resistance and stable friction factor (0,1-0,12).
