High Temperature Degradation of Nickel Based Alloys

Abstract
The addition of platinum to nickel-based alloys can have a profound effect on their oxidation and hot corrosion resistance. Improvements in gas turbine blade performance in aggressive environments are linked with the protective nature of surface oxides and coatings. However the precise role of platinum in promoting and maintaining this protection is still under active investigation and the results of several recent studies are reviewed here.
