Abstract

The oxidation behavior of Mo-ZrO₂ type and Cr-Al₂O₃ type was compared by thermogravimetric curves of hot balance, Kinetic curve of corrosion by oxidation(K-t) and weight gain-time(Δw-t) curve. The results indicated that at 700℃ in air for 70 min. the weight gain of the former was 16 times as much as that of the latter.
