Abstract: A coating method and a coated article are disclosed. Forming a coating includes providing a substrate having a substrate surface, forming on the substrate surface at least one bond coating layer defining a bond coating surface, and forming on the bond coating surface at least one oxide coating layer defining an oxide coating surface. A coated article includes a substrate having the coating formed thereupon. The oxide coating layer is more resistive to increasing the oxide coating surface roughness (Ra) than either the bond coating layer is resistive to increasing the bond coating surface roughness (Ra) or the substrate is resistive to increasing the substrate surface roughness (Ra).

Abstract: A gas turbine process includes supplying a fuel to a gas turbine, combusting the fuel in the gas turbine with a hot gas path temperature reaching at least 1100° C. during operation of the gas turbine, and supplying an inhibition composition including at least one yttrium-containing inorganic compound to interact with the vanadium and inhibit vanadium hot corrosion in the gas turbine caused by vanadium as a fuel impurity in the fuel. A process includes supplying an inhibition composition including at least one yttrium-containing inorganic compound to a hot gas path or a combustor of a gas turbine. A fuel composition includes a fuel including at least one fuel impurity including vanadium and an inhibition composition including at least one yttrium-containing compound. An atomic ratio of yttrium to vanadium in the fuel composition is in a range of 1 to 1.5.
