摘　　要：以SAF2906超级双相不锈钢材料为研究对象，分析了在铸态、固溶态、深冷态以及时效态下，该材料在人工海水环境中的电化学阻抗图谱及微观组织。结果表明，深冷处理后的不锈钢材料具有更强的耐腐蚀性。With SAF2906 super duplex stainless steel as research object, the electrochemical impedance spectra and microstructure of the steel samples in as-cast, solution treatment, cryogenic and aging state were investigated. The results show that the corrosion resistance of the stainless steel after cryogenic treatment is strongest than those after the other treatment processes.
