The application of bi-polar electrochemistry produces a linear potential gradient between two feeder electrodes, allowing the full spectrum of anodic to cathodic reaction kinetics to be controlled. A modified bi-polar approach is introduced, by superimposing a constant electrochemical potential on the potential gradient, thereby controlling the location and spatial distribution of anodic to cathodic reactions along the exposed sample surface. Application of this approach is demonstrated by controlling the extent of pitting corrosion in austenitic stainless steel as a function of the applied potential.

改进的双极电化学方法在确定点蚀特性方面的应用

双极电化学的应用在两个进料电极之间产生线性电势梯度，从而可以控制阳极到阴极反应动力学的整个光谱。通过将恒定的电化学势叠加在电势梯度上，从而控制沿暴露的样本表面的阳极到阴极反应的位置和空间分布，引入了一种改进的双极方法。通过控制奥氏体不锈钢中的点蚀程度作为施加电位的函数，证明了该方法的应用。
