Abstract
The transient oxidation behaviour of a nickel-base superalloy in different oxygen partial pressures studied using electron and ion microscopy showed that at high pO2, a triple-layered oxide developed: outer nickel oxide, then a complex aluminium-chromium oxide, and inner alumina layer. Lower pO2 produced only alumina, as reduced oxygen activity suppressed nickel oxide formation. An aluminium-depleted region in the alloy with width proportional to pO2 was observed.
