## Abstract The oxidation and carburization of two 20 Cr 30 Ni alloys with nominally 0 and 0.5 wt % Si have been investigated by cyclic exposure to carbon monoxide and carbon dioxide at 1000ยฐC. In carbon monoxide a chromium oxide film is formed which inhibits further carbon deposition. In carbon d
