Abstract (en)

A method for enhancing oxidation resistance and hot gas corrosion of a Co-based component for use in a gas turbine engine hot section. The Co-based component is aluminided to form a CoAl layer on the surface thereof. A Pt layer is then applied on top of the CoAl layer. The Pt layer is diffused into the CoAl layer to form a PtAI imparting oxidation resistance and hot gas corrosion resistance to the component.
