摘要: <正> 孔蚀的发生与发展一直是国内外许多研究工作者感兴趣的问题。在孔蚀发生敏感位置的研究中,对晶界与硫化物夹杂物研究得较多,而对非金属夹杂物方面的研究就比较少,因此我们探讨了00Cr11Ni10Mo2Ti不锈钢中非金属夹杂物的类型、大小、分布与孔蚀发生的关系。

Abstract：The type, distribution and size of inclusions in stainless steel 00Cr11Ni10 Mo2Ti were studied by a combination of techniques with scanning electron microscopy, electron probe analyses and metallography. The site susceptible to pit initiation was observed on the surfaces of electrochemically polarized specimens under the long focus microscope. The results indicate that pits initiate at the edge of nonmetallic inclusions. Under the experimental condition, TiN is more susceptible to pitting initiation than Al_2O_3; geometric factors such as size, shape and distribution of the inclusions also affect the pitting susceptibility obviously.
