An article (20) includes a substrate (28, 30) and a composite material (22) bonded to the substrate (28, 30). The composite material (22) includes a matrix (40) consisting of a metallic alloy having a solidus temperature of at least about 700 °C and a plurality of unstabilized zirconium oxide particles (42) 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 (62), and applying the mixture (62) as a heterogeneous composite material (22) to a substrate (28, 30) to form the article (20). The step of applying occurs at an application temperature of greater than the solidus temperature of the metallic alloy.
Cette invention concerne un article (20) comprenant un substrat (28, 30) et un matériau composite (22) collé sur le substrat (28, 30). Le matériau composite (22) comprend une matrice (40) constituée par un alliage métallique dont la température </= Solidus >/= est d'au moins 700 DEG C environ et une pluralité de particules d'oxyde de zirconium non stabilisé (42) réparties dans l'alliage métallique. Pour préparer l'article (20), on combine un précurseur de l'alliage métallique et la masse de poudre d'oxyde de zirconium non stabilisé en un mélange (62) que l'on applique comme matériau composite hétérogène (22) sur un substrat (28, 30). L'opération d'application se déroule à une température supérieure à la température </= Solidus >/= de l'alliage métallique.
