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 silicone bond coat composition having a viscosity of less than 1,600 centistokes is applied to substantially all external surfaces of the article and then cured. A liquid silicone elastomer outer coat composition comprising a high viscosity first liquid silicone elastomer formulation and a low viscosity second liquid silicone elastomer formulation is then applied and cured to provide a protected article having a complex shape. Optimal coatings result from a careful balancing of component viscosities. In an embodiment, the first formulation has a viscosity greater than 300,000 centistokes, and the second formulation has a viscosity less than 6,000 centistokes, and the liquid silicone elastomer outer coat composition comprises from about 60 to about 40 percent by weight of the first formulation and from about 40 to about 60 percent by weight of the second liquid silicone elastomer formulation.

Abstract: A coated article and a method for producing a coating are disclosed. Producing the coating includes providing a substrate defining a substrate surface having a substrate erosion resistance and applying a matrix and ceramic particles to the substrate surface. The matrix includes an anodic material having an anodic erosion resistance. The ceramic particles include a first ceramic having a first ceramic erosion resistance and a second ceramic having a second ceramic erosion resistance. The first ceramic erosion resistance is greater than the second ceramic erosion resistance, greater than the anodic erosion resistance, and greater than the substrate erosion resistance. The second ceramic interacts inchoately with the anodic material during the applying to form modified ceramic particles and modified anodic material formations. The modified ceramic particles are capable of forming a passive oxide film. The coated article includes the substrate and the coating on the substrate surface.
