Abstract

Three austenitic stainless steels and two Ni base heat resistant alloys were exposed to simulated environment of a waste pyrolysis and gasification treatment system for times of up to 1000 hours at 973K. These tested materials show not only hot corrosion but also oxidation. The oxide layers were consisted only of the chromium and silicon oxide, and not formed of iron and nickel oxide. The oxidation mechanism in the tested environment was discussed in point of the comparison oxygen partial pressure of the environment with the dissociation pressure of those oxides.
