摘要：

Anodic nickel dissolution in acidic chloride solutions (constant ionic strengths of 1 and 5M) over a wide range of H+ and Cl- concentrations has been investigated. Anodic dissolution in low [H+]-chloride solutions is accelerated by both Cl- and OH- with Tafel slopes of about 2.303 RT/F. On the other hand, anodic dissolution in highly acidic-concentrated chloride solutions is accelerated by both H+ and Cl- with first-order dependence on both H+ and Cl- with Tafel slopes of about 2.303 RT/F. Mechanisms, which are consistent with the empirical rate equations, are proposed. © 1979, The Electrochemical Society, Inc. All rights reserved.
