Abstract
There is provided an improved plasma spray powder composition for producing bearing surface alloy on a metal substrate, e.g. cast iron, said powder being characterized by the presence therein of a substantial amount of iron, molybdenum and a relatively small amount of silicon. Carbon may also desirably be present in the powder. When plasma sprayed, these powders yield a coating on a metal substrate, e.g. a cast iron piston ring, which is wear and scuff resistant.
