摘要
通过动电位极化、恒电位集气方法研究对纯铝在０．５ｍｏｌ／ＬＮａＣｌ溶液中的电化学行为，添加Ｉｎ３＋后，使铝的活化电位负移，并且降低铝的负差数效应系数，提出铝溶解的动力学机制．
The electrochemical behavior of Aluminum in 0.5mol/L NaCl solution was studied by potentiodynamic method and potentiostatic hydrogen gathering measurement. When high hydrogen evolution overpotential metal ion In 3+ was added in the solution , the active potential of aluminum shifted negatively and the negative difference effect (NDE) of aluminum dissolution decreased. The procedure and the influence of In 3+ added on NDE was discussed and verified by EIS .
