ABSTRACT:
High performance alloy structures are improved in corrosion and erosion and wear resistance characteristics by the incorporation of an interdispersed phase and a ternary or quaternary alloy of platinum, rhodium or palladium, the alloy base metal and an alloying element such as aluminum in the structure surface with the use of relatively less of the precious metals for a given depth of case by virtue of the conjoint incorporation of the interdispersed phase.
