Abstract
A process for the manufacture of a coated combustion component. The process includes spraying one or more liquid or powdered precursors into a high temperature thermal jet directed to a surface of a combustion component and forming a surface coating derived from the precursors to provide the coated combustion component. The surface coating may comprise a phosphate glass or a silicate glass. The surface coating may have a coefficient of thermal expansion from 3 to 26 ppm/K. A coefficient of thermal expansion of the combustion component may be greater than or equal to the coefficient of thermal expansion of the surface coating. The spraying may comprise solution spraying, powder thermal spraying, suspension thermal spraying, or a combination thereof.

A process for the manufacture of a coated combustion component, the process comprising:
- spraying one or more precursors into a high temperature thermal jet directed to a surface of a combustion component, wherein the spraying is selected from solution spraying, powder thermal spraying, suspension thermal spraying, or a combination thereof;
- and
- forming a surface coating derived from the one or more precursors to provide the coated combustion component,
- wherein the surface coating comprises a phosphate glass or a silicate glass,
- wherein the surface coating has a coefficient of thermal expansion from 3 to 26 ppm/K, and
- wherein a coefficient of thermal expansion of the combustion component is greater than or equal to the coefficient of thermal expansion of the surface coating.
