ABSTRACT:
This invention relates to high-temperature, oxidation-resistant refractory materials or alloys and to a method of preparing said alloys which have an outer skin containing at least one noble metal, e.g., platinum, and/or silver, in amounts greater than the amount of noble metal present in the alloy beneath said skin. The alloy comprises at least one noble metal selected from the group consisting of platinum, gold, silver, rhodium, iridium and palladium. The noble metal is added in amounts ranging from 0.1 to 15% by weight of the total composition to hafnium or to hafnium containing from about 0 to 50% by weight of zirconium, and heated to temperatures ranging from about 1000.degree.F to 3800.degree.F in an oxidizing atmosphere.
