摘　　要：本文首先简单总结了点蚀的产生阶段,即点蚀形核和点蚀扩展,同时介绍了夹杂物对低合金钢耐点蚀性能影响常见的研究手段,然后叙述了添加稀土元素后低合金钢中夹杂物的改变,最后阐述了低合金钢中三种常见的非金属夹杂物对钢基体的点蚀形成机理。This paper first briefly summarizes the stages of pitting corrosion,namely pitting nucleation and pitting propagation,and introduces common research methods on the influence of inclusions on the pitting corrosion resistance of low-alloy steel,then describes the changes of inclusions in low-alloy steel after adding rare earth elements,and finally expounds the pitting corrosion formation mechanism of three common non-metallic inclusions in low-alloy steel.

关 键 词：点蚀 夹杂物 稀土元素 低合金钢
