摘要
通过对穿孔泄漏的凝汽器黄铜管进行化学成分分析 ,力学性能测试、金相检验及扫描电镜能谱分析。结果表明 ,黄铜管穿孔泄漏主要是由于在冷却水介质作用下产生点状脱锌腐蚀所致 。
From a chemical composition analysis,mechanical properties test,meta llographic examination and SEM analysis,the results show that the main reason f o r the perforation of the brass-tube was Zinc-shed corrosion under the cooling-wa terThe improvement measures are put forward
