Abstract: A submersible pump component is provided. The component includes a substrate including an outer surface in a plurality of orientations, wherein a first portion of the outer surface is configured to be worn by a first wear mechanism, and a second portion of said outer surface is configured to be worn by a second wear mechanism. The component also includes at least one layer of a first coating applied to the outer surface, and at least one layer of a second coating applied over said first coating at said second portion of said outer surface. The first coating is configured to inhibit the first wear mechanism at the first portion of the outer surface, and the second coating is configured to inhibit the second wear mechanism at the second portion of the outer surface.

Abstract: Methods for repairing flange bolt holes and the resulting flange bolt holes are provided. The methods and products include the incorporation of a coating system comprising a corrosion resistant layer, which can be formed by resistance plug welding, slurry or sol-gel processing, or thermal/cold spray processing. The corrosion resistant layer can be a super alloy or ceramic material and is different than the base material of the flange bolt hole. Corrosion of the flange bolt hole can be reduced or prevented from occurring with the use of the coating system.

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.
