对工业纯Al在中性NaCl溶液中孔蚀的发展过程进行了初步探讨 ,采用了恒电位阳极极化方法测定了不同浓度的NaCl溶液中和不同极化电位下孔蚀发展的i～t曲线 ,分析了孔蚀发展前期和后期氯离子浓度和极化电位的影响 ,借助原子吸收光谱从物质分析的角度对腐蚀产物进行了研究
The development of pitting corrosion in commercial pure Al in neutral NaCl solution was discussed. The potentiostatic anodic polarization method was used to determine the i ~ t curve of pitting corrosion under different concentrations of NaCl solution and different polarization potentials , The influence of chloride ion concentration and polarization potential at the early and late stages of pitting development was analyzed. The corrosion products were studied from the point of view of material analysis by atomic absorption spectrometry
