Abstract
Discloses a composite metal body having an oxide-dispersion-strengthened substrate made by mechanical alloying and a high chromium-aluminum nickel- or cobalt-base coating on the substrate. The substrate is characterized by containing an amount of aluminum effective to react with oxygen and nitrogen within the body of the substrate to prevent migration of these gases to the interface of substrate and coating and to thereby inhibit spalling of the coating.
