FIELD: metallurgy.
SUBSTANCE: surface coating contains 0.0001-1 wt % potassium and/or sodium and has thickness from 1 micrometer till 2 mm, can contain phosphorus and 0.1-0.9 of carbon, 0.1-10, at least one of Mo, Ni, Cr and Cu, 0.1-3, at least, one of Mn, Si, V, Nb, W, Al, Ti, Ca and S. Internal part can contain, wt %: 0.1-0.9 carbon; 0.1-10, at least, one of Mo, Ni, Cr and Cu; 0.1-3, at least one of Mn, Si, V, Nb, W, Al, Ti, Ca and S. Alloy is received by means of forming on internal surface cavity of die it is formed film from used salt in the capacity of lubricant, cavity of mold is filled by initial material, pressed and sintered.
EFFECT: alloy allows high density, surface hardness and resistance against wear while friction.
