ABSTRACT:
A method of making an anti-friction coating on a metal surface subject to sliding wear, including the steps of: forming an encapsulated powder having grains made of a core of solid lubricants including at least graphite and MoS.sub.2 (others may include BN, NaF, LiF, CaF.sub.2, and WS.sub.2), and a thin shell of fusable soft metal such as Ni, Co, Fe, Zn, Sn, Mg, or Cu; plasma spraying the powder onto a light metal surface, such as a cylinder bore wall of an internal combustion engine, to form a coating; and finish-smoothing the coating to a uniform thickness of about 25-175 microns. Some core particles may be hard, wear-resistant particles such as SiC, NiCrAl, FeMn, FeCrAl, FeWNiVCr, NiCrMoVW, FeCrMoWV, CoFeNiCrMoWV, NiCrMoV, and CoMoCrVW.
