abstract = {The oxidation behavior of the nickel base Alloy 602 CA in
atmospheres, relevant to gas separation units in fossil
fired power plants, was investigated in the temperature
range 800 to 1100 °C. Isothermal oxidation kinetics were
determined in Ar–7 $\%H2O,$ Ar–4 $\%H2–7$ $\%H2O,$
Ar–20 $\%O2–7$ $\%H2O$ and, for comparative purposes, in
Ar–20 $\%O2.$ The alloy formed an external alumina scale
during oxidation at 800 °C, regardless of the atmosphere.
Increasing the temperature results in gradual replacement of
the alumina scale by an external chromia layer and internal
alumina precipitates. The chromia growth rate is affected by
the gas composition, due to titanium incorporation in the
scale and outwardly protruding metallic nodules. The
external alumina scale formation was strongly affected by
surface cold work during specimen grinding. This effect,
which promoted external alumina scale formation, was
retained during exposure at 800 °C but was rapidly lost at
higher temperatures resulting in external chromia scale
formation and internal oxidation of aluminum.},
