Abstract

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.
