Characterization of Hot-Steam Oxidation Tested Chromosiliconized Heat-Resistant Austenitic Stainless Steel

In this study, a duplex chromizing-siliconizing coating was produced on heat-resistant austenitic stainless steel by pack cementation. The chromizing-siliconizing of the duplex chromosiliconized coating was evaluated in 873 K hot steam for 3.6 × 103 ks, and the oxidized as well as the coated samples were characterized. A duplex chromosiliconizing coating has been successfully applied to heat-resistant austenitic stainless steel by pack cementation. This coating containing Cr and Si can effectively improve the oxidation resistance of heat-resistant austenitic stainless steel in 873 K hot steam for 3.6 × 103 ks.
