A bearing member such as a piston ring for internal combustion engines having a wear resistant alloy coating applied to its wear surface by plasma spraying an aggregate mixture of particles thereon. The mixture is made by first alloying carbon, silicon, chromium, nickel, iron, and boron together to form intermetallic brazing and binding alloy particles and by alloying substantially 75% cobalt and 25% molybdenum to form cobalt-molybdenum alloy particles, for mixing with individual particles of pure molybdenum. These three different particles form the aggregate mixture to be sprayed on the bearing surface.
