针对金属铜在中性水介质中的腐蚀问题，采用旋转挂片腐蚀试验和电化学方法对模拟水样中铜的腐蚀行为进行的研究。实验表明：流速和温度均对铜的腐蚀有影响。随着流速和温度的升高，溶液中溶解氧的扩散速度加快，电荷传递电阻减小，导致铜的腐蚀速率加快，但是在高温区，氧的溶解度成为影响铜腐蚀的主导因素，而温度的升高使得溶液中去极化剂溶解度减小，因而在高温区出现了铜的腐蚀速率减小的现象。

According to the corrosion and scaling problems of copper in neutral aqueous solution, study corrosion behavior of copper in simulated water by using rotating hang piece of corrosion test and electrochemical method. Experiments show that flow velocity and temperature have an effect on the corrosion of cupper. Along with the increase of temperature and velocity, the diffusion of dissolved oxygen in solution speed up, the charge transfer resistance reduction, leading to the corrosion rate of copper faster. But in the high-temperature region, solubility of oxygen becomes the dominant factors of copper corrosion, and the rise of temperature reduces the solubility. Thus in the high-temperature region appeared copper corrosion rate of decrease phenomenon.
