摘要
发展了两种用于研究孔蚀发生发展及其缓蚀作用的电化学方法：恒电位开路衰减响应技术和研究蚀孔发展状态的时电位法．结果表明前者可准确反映缓蚀剂在金属表面上的吸附特征，并了解孔蚀的诱发和产生过程．后者可定性反映孔蚀发展程度及缓蚀剂对孔蚀发展的抑制作用，但有待进一步完善．
Two electrochemical methods have been developed for studying the pitting initiation, pitting propagation and inhibition. They are potentiostatic open\|circuit relaxation curves and chronopotential method. The results show that the former can correctly reflect the absorption of the inhibitor on the metal surface and the display the pitting initiation and pitting propagation. The latter can qualitatively reflect the level and the inhibition of pitting propagation , while this method needs to be further improved.
