摘要
本文在实验室对钝态不锈钢小孔腐蚀试验的结果,进行统计理论分析,表明孔蚀最大深度的分布符合极值Ⅰ型分布规律.并以此规律为依据,对现场不锈钢热交换管的泄漏情况进行讨论。
The result of the pitting corrosion experiment on the passive stainless steel in the laboratory is analysed with statistical theory. It shows that the distribution of the maximum depth of the pitting corrosion is coincident with the gumbel type I maximum distribution law.Based on the law,the author discusses the leakage of the heat exchanger pipes of stainless steel on the worksite and its result also coincides in the practical conditions.
