A study of the kinetics of electrochemical dissolution of aluminum alloys in alkaline electrolytes

Electrochemical dissolution of aluminum alloyed with tin, indium, and lead in a NaOH solution in the concentration range 4.4–12.0 M at 75°C was studied by the method of chronopotential and current-voltage curves. The influence exerted by alloying elements on the electrochemical parameters of the process was revealed.
