摘要：

The transient oxidation behaviour of a nickel-base superalloy in different oxygen partial pressures studied using electron and ion microscopy showed that at high pO(2), a triple-layered oxide developed: outer nickel oxide, then a complex aluminium-chromium oxide, and inner alumina layer. Lower pO(2) produced only alumina, as reduced oxygen activity suppressed nickel oxide formation. An aluminium-depleted region in the alloy with width proportional to pO(2) was observed.
