摘要：

The electrochemical behaviour of tin in 0.5 M citric acid solution was studied by electron microscopy techniques in addition to the potentiodynamic method. The observed electrochemical dissolution is quite similar to pure chemical dissolution when metallographic practices are used and takes place distinctly between the grains. The film growing process follows a dissolution/precipitation mechanism. The local reactivation process occurs primarily along the tin grain boundaries locations.
