Article Preview

The kinetics and products of oxidation of ternary Co-10Cr-5Si alloys in 1 atm of pure O2 at 700 and 800°C were investigated. The scales were composed of an outer CoO layer and an inner complex layer consisted of cobaltous oxide, Cr2O3 and SiO2. Internal oxidation zones were found beneath the nodules formed at 800 °C. However, there was no internal oxidation zone present beneath the scales formed at 700°C.
