铜在醋酸介质中腐蚀行为及其缓蚀剂缓蚀行为的电化学研究

open access: yes, 1990
本文利用循环伏安典线。动电位极化曲线和交流阻抗频谱方法研究了铜在醋酸系列介质中的腐蚀行为.不但研究了铜的阳极溶解过程。而且还研究了其阳极还原过程、包括氧的还原过程,并且研究了醋酸浓度.溶解氧浓度。Cl-离子和温度对此腐蚀的影响。结果表明腐蚀的阳极过程—铜的溶解不是一个可逆过程。在无水冰醋酸中受Cu(I)扩散与控制。在水落液中受传荷控制。铜表面上的膜(氧化膜、阴离子、吸附层和盐层)不致密。只是一种类似于有一定漏电性质为电介质。易被O2、H2O、Cl-和高温破坏.不能完全阻止铜的溶解和腐蚀 ...

2205钢在模拟深海热液区中的腐蚀行为

open access: yes, 2018
利用交流阻抗法、线性极化法、动电位极化法及Mott-Schottky分析法,研究了2205钢在不同温度、20 MPa静水压的3.5%Na Cl溶液中的电化学性质,通过SEM、EDS及白光干涉仪分析了电化学测试后2205钢的腐蚀形貌及腐蚀产物。结果表明,在模拟深海热液区环境中,2205钢在25℃下具有良好的耐点蚀能力;溶液温度达到65℃时,2205钢表面会出现明显的点蚀现象;溶液温度达到150和200℃时,2205钢表面会产生裂纹状点蚀坑;65℃时,点蚀坑主要发生在奥氏体相内,100~200℃时 ...
