and aluminum alloys are popular nonferrous metals in industrial application. Protective oxide films are formed spontaneously on their surfaces under air condition, which makes the metal base more resistive to corrosion. However aluminum and its alloys are susceptible to pitting corrosion in chloride environments owing to the breakdown of the oxide layers. There were some reports on pitting corrosion[4-7......
