Abstract
Abstract A bearing member, e.g., a piston ring, for use in an internal combustion engine at temperatures up to 1,200* F having a wearresistant coating from 0.010 to 0.020 inches finished thickness flame-sprayed on a wear surface thereof, such coating, before spraying, preferably consisting of an admixture of 34.4 parts by weight of elemental nickel particles jacketed with 8.6 parts by weight of elemental aluminum with the balance being 57 parts by weight of titanium dioxide, such particles sized to pass through a 120 mesh screen but not through a 325 mesh screen.
