文摘

Pre-oxidation treatment in argon gas containing 0.1 ppm to 1 volume % oxygen improves oxidation resistance of 9 mass% Cr steel in steam at 650 °C. A thin scale of Cr2O3-rich oxides is formed on the surface of 9Cr steel by the pre-oxidation treatment.The addition of Si enhances the formation of Cr2O3-rich oxide scale.
