摘要：
Corrosion and chromium evaporation from commonly used metallic interconnects in humidified oxidizing environment during SOFC operation remains an issue. We have studied the role of pretreatment of AISI 430 alloy with or without nickel coating on the oxidation resistance and formation of interfacial compounds at 650-800 degrees C in moisture-saturated air. It is found that electro deposited nickel coated AISI 430 alloy pretreated in dry hydrogen (Ar-3% H2) improves the oxidation resistance but not pre-oxidized alloy. The underlying mechanisms for improved oxidation resistance are discussed using structural and microstructural analysis.
