ABSTRACT Corrosion resistance of materials in different environments is related closely to the phases formed on the material. Alloys containing iron, chromium, and nickel, such as stainless steel, form a chromium oxide (Cr2O3) on their surface at low temperatures. However, at elevated temperatures other oxide phases may form at the surface of the alloy.
