Abstract: A coated article and a method for producing a coating are disclosed. The method for producing a coating includes providing an iron-based alloy substrate, and depositing a protective coating over a surface of the iron-based alloy substrate. The protective coating includes a cobalt-chromium-based coating material having at least one anodic element distributed therein. The at least one anodic element being anodic to the iron-based alloy substrate. Another method for producing a coating includes providing an iron-based alloy substrate, depositing an underlayer including at least one anodic element over a surface of the iron-based alloy substrate, and depositing a top coat including a cobalt-chromium-based coating material over the underlayer. The at least one anodic element being anodic to the iron-based alloy substrate. The coated article includes a protective coating having at least one anodic element distributed therein deposited over a surface of an iron-based alloy substrate.

Abstract: A plated component and a plating process are disclosed. The plating process includes applying a material to a region of a component, the material being selected from the group consisting of nickel, cobalt, chromium, iron, aluminum, or a combination thereof. The region includes a single crystal microstructure, includes a directionally solidified microstructure, is substantially devoid of equiaxed microstructure, or a combination thereof. The applying includes electroplating, electroless plating, or the electroplating and the electroless plating. The plated component includes an electroplated region, an intermediate layer on the electroplated region, and an overlay coating on the intermediate layer.

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.
