Abstract

Cyclic thermogravimetric analysis (CTGA) provided a quantitative assessment of cyclic oxidation kinetics for a Ni–22Al–15Pt + 1 wt.% Hf alloy. This alloy showed a very low extent of oxide spallation and a slow oxidation rate. The adherent oxide thickness calculated from observed weight changes (due to both oxidation and scale loss) was found to be very similar to the directly measured scale thickness. It is concluded that a previously developed description of cyclic oxidation thermogravimetry is applicable, and that the alloy exhibits excellent performance.
