Abstract
An article includes a substrate and a composite material bonded to the substrate. The composite material includes a matrix consisting of a metallic alloy having a solidus temperature of at least about 700° C. and a plurality of unstabilized zirconium oxide particles distributed throughout the metallic alloy. The article is prepared by combining a precursor of the metallic alloy and the mass of unstabilized zirconium oxide powder to form a mixture, and applying the mixture as a heterogeneous composite material to a substrate to form the article. The step of applying occurs at an application temperature of greater than the solidus temperature of the metallic alloy.
