摘要
应用环境扫描电镜和能谱分析仪的现代分析手段 ,对D 1 5 0mm补偿器使用泄漏失效原因进行了分析。结果表明 ,使用环境中存在S2 - 、Cl-
D150 leaking compensator is analyzed by means of environment scanning electron microscope and energy depressive spectroscopy. The conclusion is that the reason for leaking was existing of the element S^(2-)?Cl^- in working environment which give rise to corrosion craze under tensile stress.
