Title: METHOD OF FORMING THERMAL BARRIER COATING, THERMAL BARRIER COATING FORMED THEREBY, AND ARTICLE COMPRISING SAME
Abstract:
A thermal barrier coating that includes a YAG-based ceramic is prepared by a solution precursor plasma spray method that includes injecting a precursor solution into a thermal jet, evaporating solvent from the precursor solution droplets, and pyrolyzing the resulting solid to form a YAG-based ceramic that is melted and deposited on a substrate. The thermal barrier coating can include through coating-thickness cracks that improve the strain tolerance of the coating.
