Abstract: An optical coating is applied to an article surface of an article by providing a deposition substrate other than the article surface, wherein the deposition substrate is made of a removable material. The optical coating is thereafter deposited onto the deposition substrate. The optical coating is thereafter transferred to the article surface using a transfer support, which may be the deposition substrate or may be a different piece. The method includes thereafter affixing the optical coating to the article surface, and thereafter removing the transfer support.

Abstract: A corrosion resistant tape coating for gas turbine engine includes a glassy ceramic matrix wherein the glassy matrix is silica-based, and includes corrosion resistant particles selected from refractory particles and non-refractory MCrAlX particles, and combinations thereof. The corrosion resistant particles are substantially uniformly distributed within the matrix, and provide the coating with corrosion resistance. Importantly the coating of the present invention has a coefficient of thermal expansion (CTE) greater than that of alumina at engine operating temperatures. The CTE of the coating is sufficiently close to the substrate material such that the coating does not spall after frequent engine cycling at temperatures above 1200° F.

Abstract: An optical coating is applied to an article surface of an article by applying a first release system to a deposition substrate, and depositing the optical coating onto the deposition substrate. A second release system and transfer substrate is applied to the second face of the optical coating. The first release system is dissolvable in a first-release-coating solvent that does not dissolve the second release system. The first release system is dissolved in the first-release-coating solvent that does not dissolve the second release system, to separate the optical coating from the deposition substrate. The first face of the optical coating is affixed to the article surface, and the transfer substrate is separated from the optical coating. Any of a variety of affixing techniques may be used.

Abstract: A method of applying a heat-rejection coating directly on a substrate of a metallic component is disclosed. The steps include supplying a metallic component, such as of a gas turbine engine, before applying a reflective-coating mixture onto the component, wherein the reflective-coating mixture comprises a metallic pigment and a reflective-coating-mixture carrier, and wherein the step of applying is accomplished by a method selected from the group consisting of air-assisted spraying, airless spraying, brushing, and decal transfer. The component having the reflective-coating mixture thereon is fired to form a reflective coating on the component.

Abstract: A heat-rejection coating is applied to a metallic component of a gas turbine engine, preferably made of a nickel-base superalloy. A component surface is preferably pre-treated, as by polishing the component surface, thereafter pre-oxidizing the component surface, and thereafter applying a ceramic barrier coating onto the component surface. A reflective-coating mixture is air sprayed onto the pre-treated component surface. The reflective-coating mixture includes a metallic pigment, such as platinum, gold, palladium, and alloys thereof, and a reflective-coating-mixture carrier. The component with the reflective-coating mixture sprayed thereon is fired.
