PROBLEM TO BE SOLVED : To provide components protected with corrosion-resistant coatings and methods for making the components to mitigate hot corrosion of engine components.
SOLUTION : A gas turbine engine component 100 includes a substrate 102 formed of a high temperature resistant material and a corrosion resistant layer 106. The corrosion resistant layer is inert to molten salt impurities and includes a refractory metal vanadate of chemical formula MxVyOz, where M is selected from the group consisting of alkaline earth metals, group IV and V transition metals, rare-earth metals and their combinations, and where either z=x+2.5y, z=1.5x+2.5y or z=2x+2.5y is satisfied.
