摘要： A method for protecting a coating on a surface of a component is provided. The method includes a coating step that coats at least a portion of the component with a ceramic slurry. A projecting step projects a pattern of light onto the component with a lithographic process to expose and solidify a ceramic layer. A removing step removes unexposed portions of the ceramic slurry from the component. The ceramic layer comprises multiple stress raising elements or multiple anchoring elements.

摘要： A method of controlling an extent of a thermal barrier coating (TBC) sheet spall and a hot gas path (HGP) component are disclosed. The method provides an HGP component having a body with an exterior surface. Controlling the extent of the TBC sheet spall includes forming a TBC over a selected portion of the exterior surface of the body. The TBC includes a plurality of segments in a cellular pattern. Each segment is defined by one or more slots in the TBC, and each segment has a predefined area such that the extent of the TBC sheet spall is limited by the predefined area of each of the plurality of segments that constitute the TBC sheet spall.

摘要： A high-temperature, high-strength, oxidation-resistant cobalt-nickel base alloy is disclosed. The alloy includes, in weight percent: about 3.5 to about 4.9% of Al, about 12.2 to about 16.0% of W, about 24.5 to about 32.0% Ni, about 6.5% to about 10.0% Cr, about 5.9% to about 11.0% Ta, and the balance Co and incidental impurities. A method of making an article having high-temperature strength, cyclic oxidation resistance and corrosion resistance is disclosed. The method includes forming a high-temperature, high-strength, oxidation-resistant cobalt-nickel base alloy as described herein; forming an article from the alloy; solution-treating the alloy by a solution heat treatment; and aging the alloy by providing at least one aging heat treatment at an aging temperature that is less than the gamma-prime solvus temperature, wherein the alloy is configured to form a continuous, protective, adherent oxide layer on an alloy surface upon exposure to a high-temperature oxidizing environment.

摘要： A cold spray coating process is disclosed. The cold spray coating process includes positioning a cold spray nozzle relative to a bearing assembly, rotating the bearing assembly, and directing a powdered babbitt material through the cold spray nozzle, to a surface of the rotating bearing assembly. The powdered babbitt material adheres to the surface of the rotating bearing assembly, forming a coating on the surface. Another cold spray coating process includes positioning the cold spray nozzle relative to a bearing assembly, rotating the cold spray nozzle, and directing a powdered babbitt material through the cold spray nozzle, to a surface of the bearing assembly. The powdered babbitt material adheres to the surface, the rotating of the cold spray nozzle forming a coating on the surface. Another cold spray coating process includes monitoring properties of the coating on the surface of the bearing assembly with a coating monitor.
