摘要：

The kinetics of anodic film growth on six types of freshly generated stainless steel surfaces have been investigated electrochemically as a function of electrode potential and electrolyte composition. Repassivation of a scratch scar showed that initial growth of a passive film is controlled by ion migration in a high electric field obeying an inverse logarithmic rate law at passive potentials. The rate of growth was dependent on the electrode potential and the chloride ion concentration in the electrolyte. Three kinetically distinct regions were observed and are discussed in terms of film growth, film dissolution and pitting. © 1990 Chapman and Hall Ltd.
