Abstract
The effect of small amount gallium (up to 0.06%) on the corrosion behavior of pure aluminum (99.99%,4N) in chloride solution was investigated using a potentiodynamic polarization technique.It has been found that the open circuit corrosion potential and the pitting potential shifted in the active (negative) direction with increasing gallium content,while corrosion rate and pitting occurrence factor for aluminum increased.The effect of gallium on the degradation of corrosion resistance is rather small while the gallium content is below 0.03mass%.The gallium content should be kept less than 0.03mass% in the pure aluminum.关键词
