A Study of the Susceptible Sites for Pitting of lCrl8Ni9Ti Stainless Steel

摘要: 本文研究了TiN夾雜對點蝕形核的影響。實驗發現1Cr18Ni9Ti不銹鋼微區點蝕形核敏感位置在TiN夾雜周圍。AES結果表明TiN夾雜周圍有一貧Cr區,Cr/Fe+Ni峰值低于基體。TiN夾雜周圍是鈍化膜的薄弱部位。TiN夾雜的存在降低了微區的點蝕破裂電位,即降低了不銹鋼的耐點蝕性能。

Abstract: The influence of the TiN inclusion on the pitting initiation has been studied. The test results shown that the susceptible sites for pitting initiation of lCr18Ni9Ti in microfield exist around the TiN inclusion. The results by AEM show that the area around the TiN inclusion is lack of Cr,its peak value of Cr/Fe + Ni vs spurttings depth curve is less than that of the site for the TiN inclusion. The sites around TiN inclusion are the valuable area of the passive film. TiN inclusion lower the value of pitting potential in microfield or the ability in pitting resisting.
