摘　　要：阳极保护方法是金属腐蚀防护中重要的电化学方法之一,其原理是向金属表面通入足够的阳极电流,使金属发生阳极极化,并处于钝化状态,从而使金属溶解大为减缓。本文利用钛金属可钝化的性质,针对我国硫酸铝生产行业中的钛金属盘管蒸发器的防腐保护,提出了一种新型阳极保护恒电位仪,文中给出了恒电位仪的主电路、控制电路及软件设计流程。实验结果显示本文给出的阳极保护恒电位仪及其控制系统具有良好的参比电压控制效果,控制简便,无需值守便可很好地对可钝化的金属提供有效的保护,在化工尤其是具有腐蚀性的化工领域,具有很好的推广价值。Anodic protection is one of the important methods among electrochemical protection to prevent metal corrosion. Its principle is to use external current to change the metal potential to slow or inhibit corrosion. Aiming at electrochemical corrosion protection for titanium evaporators in aluminum sulfate industry, A novel potentiostat was introduced in this paper through apply the nature of titanium metal can be passivated, the main circuit, control circuit and the software design flow were gave out and the testing result indicates that the new design has a good reference voltage control effect, simple control, and unattended character, which can provide effective protection to the metal can be passivated, and has very good promotional value in the chemical areas, especially those with corrosive chemicals,
