中文摘要：

烧结金属纤维多孔材料是一种优质高效新型功能材料。通过浸泡试验、动电位极化扫描、金相分析及SEM扫描电镜等试验对316L不锈钢纤维多孔材料的腐蚀机理进行了系统的研究。研究发现：晶界腐蚀和蚀坑对材料的腐蚀过程均有影响;纤维烧结点处比纤维杆处耐蚀;随着孔隙率的增大,纤维毡的腐蚀失重量增大,腐蚀程度更严重。

英文摘要：

Sintered metal fibre porous felt is a new kind of functional materials with outstanding properties. Using the methods of immersion test, electrochemical polarization, metallographic and SEM analysis, the corrosion mechanism of sintered 316L stainless steel fibre porous felts was systemically studied. It is found that the intergranular and pitting corrosions both influence the corrosion process. The corrosion resistance of sintered joints between the fibres is better than that of the fibre rod; and the felt is more severely corroded and its mass increases after corrosion as its porosity increases.
