EVALUATION OF THE EFFECT OF THE NONLINEARITY OF POLARIZATION CHARACTERISTICS ON THE DISTRIBUTION OF POTENTIAL AND CURRENT ON THE SURFACE OFELECTRODES

methods of taking into account the nonlinearity of polarization curves in calculating the distribution of the potential and current on the s urface of interacting dissimilar metals are examined. The effect of di fferent types of nonlinearities on the required characteristics is eva luated and recommendations are given on linearization of polarization curves both in the case of nonlinearities of a small order and for lar ge nonlinearities. An algorithm is proposed for numerical calculations of the distribution of current in the case of multiple-valve polariza tion curves, especially, in examining anodically passivating metals.
