Effects of La on isothermal oxidation behavior of a Ni-Cr-W-Mo heat-resistant alloy at 1173 K

Oxidation behaviors of zirconium hydride in pure oxygen at 350～600 ℃ were investigated by isothermal oxidation and the influences of temperature and oxidation time on mass increment of the oxide layer were studied.

The oxidation of high speed steel was studied at 500 ℃, 650 ℃ and 800 ℃ in the air, and the isothermal oxidation kinetics curves were obtained by thermo gravimetric analysis.
