Abstract By comparison of the antitarnishing effects of various agents, the laurylamine was found to be an excellent antitaranishing agent for tinplate. The optimum conditions of treatment were laurylamine 2.5g/L; pH=8.70℃; 10min. The results of XPS and AES analyses showed that on tinplate surface an anticorrosive coordination compound film of laurylamine was formed, and N atoms in laurylamine molecule were coordinated with Sn (II). The relative atomic percent contents (A.C.%) of the film calculated at the constat elemental composition section of the AES profile curves were O 39.0%; Sn 48.7%; N 7.9%; C 4.4%.
