Abstract: Method of making an aluminum alloy piston with a ring groove reinforcement wherein a grooved piston blank is cleaned to remove any oxide films, and a bonding metal is sprayed over the surface of the groove while the blank is at a temperature of from about 330* to 390* F., and thereafter a wear resistant metal is sprayed into the groove while the blank is still at a temperature within the aforementioned range to thereby fill the groove.
