Abstract :
A comprehensive study of ac corrosion of aluminum alloys has led to a proposed mechanism of attack based on local pH changes. A critical alternating current density of 0.5 ma/in2 has been defined below which no corrosion occurs. At higher current densities the corrosion is time dependent. Engineering design data is presented.
