摘　　要：为了考察金属多孔材料在高温气体净化中应用性能,研究了316L、301S、Fe3Al三种金属多孔材料在高温硫化氢气氛(350℃,介质:CO2+H2S(200PPM))中的硫化性能以及材料孔结构的稳定性,并利用光学显微镜观察其表面形貌,从而评价其耐蚀性能。结果表明:经过1 500 h试验,三种金属多孔材料在高温硫化氢气氛中耐腐蚀性能顺序为Fe3Al>310S>316L,三种材料的耐蚀性能差异主要由于其在腐蚀气氛中所形成的腐蚀产物不同所致。In order to investigate the performance of metal porous materials in the application of high temperature gas purification,316L,301S,Fe3Al metal porous materials at high temperature hydrogen atmosphere（350℃,medium：CO2＋H2S（200PPM）））were evaluated from the curing performance and materials pore structures,stability,and optical microscopic observation of the surface morphology.Results showed that：1 500 h test,the corrosion resistance of three kinds of metal porous material in an atmosphere of high temperature hydrogen sulfide was Fe3Al310S316L.The differences in the corrosion resistance of these materials is mainly because of their different corrosive atmosphere corrosion products formed.
