| 摘 要： | T3铜管衬套在冷挤压成型前的软化退火、酸洗后其表面产生严重腐蚀，造成整批产品报废。对该产品及其腐蚀产物进行了金相检验、化学分析等检验，综合各项检验结果并采用模拟试验的方法详细分析了产生铜腐蚀的原因和机理。试验证实，在潮湿条件下铜与氯化物、铁等金属氧化物接触时的化学和电化学腐蚀，退火加热使衬套产生了严重腐蚀。

| Abstract: | Before cold extrusion T3 copper tube surface appears serious corrosion after soften anneal and pickling, which cause the whole products rejected. The reason and mechanism of the surface corrosion of T3 copper tube were researched by using chemical composition analysis, metallographic examination. By synthesizing various testing results and using the simulation testing, the results showed that under wet condition, the copper contacted with chlorides and ion to cause chemical and electrochemical corrosion, and the heating for anneal made the copper tube corrosion seriously. |
