Abstract
The oxidation and corrosion resistance of a nickel-base alloy are enhanced by a process which includes first enriching the surface of an alloy substrate with platinum, as by electrolytic deposition, and then simultaneously diffusing aluminum and silicon from a molten state into the platinum-enriched substrate. The invention further provides coatings and coated substrates with enhanced oxidation and corrosion resistance.
