【摘要】 某空调用铜管在使用中发生穿孔渗漏。对该铜管进行了化学成分、力学性能以及扫描电镜和能谱分析等试验。结果证明,含氯、硫的冷却液对铜的腐蚀是形成铜管穿孔失效的主要原因,其它杂质元素的存在对加速失效也起了一定的作用。更多还原

【Abstract】 The copper pipe using for air-conditioner has perforated and seeped in running. The failure copper pipe was inspected by chemical composition analysis, mechanical performance testing, SEM and Energy spectroscopy. The results show that the corrosion of something containing Cl and S to copper is the dominant failure reason. In addition, some impurity elements also accelerate the failure.更多还原
