摘　　要：通过极化试验对4种低合金钢的点蚀诱发敏感性作了比较,并结合显微分析对 4 种钢点蚀诱发敏感性的差异机理做了探讨,结果表明:钢中夹杂物与合金元素是影响低合金钢点蚀诱发敏感性差异的主要原因。Pitting initiation susceptibility of four low alloy steels was compared by polarization tests. The mechanism that causes the difference in pitting initiation susceptibility is discussed based on micro-analysis. The results showed that the difference in pitting initiation susceptibility was attributed to inclusions in the steels and the addition of alloy elements to the steels.

关 键 词：夹杂物 合金元素 点蚀诱发敏感性
