用XPS和AES分析了亚磷酸三苯脂 (TP)在A3钢表面膜中的元素价态、组成、参与配位的元素 .结果表明 :膜的表面铁为二价或三价 ,氧元素为配位原子 ,P和苯环不参与配位 .膜的组成为多核配合物 .进一步分析了亚磷酸三苯脂与铁离子配位机理 .
The elemental valence, composition and coordination elements of triphenyl phosphite (TP) in the surface film of A3 steel were analyzed by XPS and AES.The results showed that the surface iron of the film was bivalent or trivalent and the oxygen was The coordination atoms, P and benzene ring do not participate in the coordination.The composition of the film is multi-core complex.Further analysis of coordination mechanism of triphenyl phosphite with iron ion.
