| 摘 要： | 本文研究了TiN夹杂对点蚀形核的影响。实验发现1Cr18Ni9Ti不锈钢微区点蚀形核敏感位置在TiN夹杂周围。AES结果表明TiN夹杂周围有一贫Cr区,Cr/Fe+Ni峰值低于基体。TiN夹杂周围是钝化膜的薄弱部位。TiN夹杂的存在降低了微区的点蚀破裂电位,即降低了不锈钢的耐点蚀性能。

| 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. |
