Abstract

A platinum-silicon powder is electrophoretically deposited on a nickel or cobalt base superalloy substrate. The deposited powder is heated to form a transient liquid phase on the substrate and initiate diffusion of Pt and Si into the substrate. An aluminum-chromium powder is then electrophoretically deposited on the Pt-Si enriched substrate and diffusion heat treated to form a corrosion- and oxidation-resistant Pt-Si enriched diffused aluminide coating on the substrate. The presence of both Pt and Si in the aluminide coating unexpectedly improves coating ductility as compared to a Pt-enriched diffused aluminide coating without Si on the same substrate material.
