摘要:

对1Cr13不锈钢点蚀电位的离散分布进行统计分析，利用点蚀发生概率、门槛电流密度和电极电位的关系，结合直线外延法推测出在极限门槛电流密度下，零概率点蚀电位，即极限零概率点蚀电位，可以作为评价材料耐点蚀性能的参数。

关键词 ：不锈钢, 点蚀电位, 门槛电流值, 点蚀, 概率

Abstract：

In order to give an exact evaluation of pitting resistance of 1Cr13 stainless steels, the discrete data of breaking potential was analyzed. By the relationship of the pitting occurrence probability, threshold value and electrode potential, a new parameter called the ultimate zero probability breaking potential was obtained. It could be used for evaluating the pitting corrosion resistance of the stainless steel.

Key words： stainless steel breaking potential threshold value pitting corrosion probability
