摘要： 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.

摘要： A method for manufacturing a coating includes dissolving at least one salt in a mixture of water and ethanol to form a precursor solution, adding an additive to the precursor solution to form a fuel solution, and injecting the fuel solution into a plasma flame. The additive includes at least one of urea or ammonium acetate. The additive functions as a fuel to increase a temperature of the plasma flame. The method further includes manufacturing the coating on a substrate. The coating includes a garnet structure including a predetermined amount of yttrium-aluminum, one or more first cracks extending completely through a thickness of the coating, and a porosity greater than ten volume percent.

摘要： Embodiments of a microstructure that allows arrest of contaminant infiltration includes an inter layer and at least one highly reactive ceramic layer. The inter layer is not reactive to an infiltrating reactive species. The HRC layer includes materials that react with a reactive contaminant species to slow or arrest infiltration of such contaminant species.
