本文采用AES分析和电化学方法,研究了10~#钢钝化膜在含NaCl碳酸钠缓冲溶液中,二元羧酸盐对孔蚀的抑制作用.结果表明,二元羧酸盐对钝化膜孔蚀有抑制作用,其抑制能力顺序为:壬二酸>癸二酸》庚二酸>辛二酸>己二酸
In this paper, the inhibitory effect of dicarboxylic acid salts on pitting corrosion of 10 ~ # steel passivation film in NaCl-containing sodium carbonate buffer solution was studied by means of AES and electrochemical methods. Pitting corrosion inhibition, inhibition of the order: azelaic acid> sebacic acid "pimelic acid> suberic acid> adipic acid
