摘要:

通过结合表征测试、腐蚀失重测试以及电化学测试方法，并模拟TP2紫铜在工业生产中的环境，以分析材料在工业环境中的腐蚀行为。结果表明，与乙酸气氛相比，TP2铜在含有甲酸的腐蚀性气氛的作用下表现出更严重的腐蚀倾向，并且有机酸浓度的增加使材料的腐蚀更加严重。此外，有机酸大气和SO₂污染物的结合对TP2紫铜表面造成了更严重的破坏，SO₂污染物含量的增加也使情况变得更为严重。与乙酸气氛和SO₂污染物的组合相比，甲酸气氛和SO₂污染物的组合对TP2紫铜表面表现出严重而复杂的腐蚀行为。

Abstract：

With excellent electrical and thermal conductivity, TP2 copper has a wide range of applications in industrial production process. During the practical production process, a large amount of organic acid pollutants containing carboxylic acid ions will be generated. Meanwhile, as a result of the defects of TP2 copper and the impact of moisture and corrosive media in the external environment, the content of organic acid pollutants in operating ambient of TP2 copper is at the high level, which may accelerate the occurrence of organic acid corrosion on the surface of TP2 copper. In order to simulate the organic acids induced corrosion behavior of TP2 copper in industrial environments, the TP2 copper was assessed via immersion tests in solutions with different organic acid concentrations temperature-cyclically, by means of measurements of mass loss Tafel polarization and electrochemical impedance, as well as SEM characterization. The results show that in comparison to the acetic acid containing atmosphere, TP2 copper exhibits stronger corrosion tendency in the formic acid containing ones, while the higher the organic acid concentration, the much severe the corrosion of the TP2 copper. In addition, the combination of the organic acid containing atmosphere and SO₂ pollutants may cause much severe corrosion damage of the TP2 copper surface, and the higher content of the SO₂ pollutants, the severe the corrosive conditions. Besides, much severe corrosion and complexity of the corrosion behavior emerged on the surface of the TP2 copper in the atmosphere of co-existance of SO₂ pollutants and with formic acid rather than that with acedic acid.

Key words： TP2 copper organic acids SO₂ contaminants electrochemical behavior
