摘　　要：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 .Composition and valences of the elements in the triphenyl phosphite film formed on the surface of A3 steel were analyzed by means of XPS and AES.The results show that Fe on the surface of the film is +2 or +3 valence;that O atom is the coordinate ligand while P and benzene ring do not coordinate;and the composition of the film is polynuclear complex.The mechanism of coordination of triphenyl phosphite with Fe is suggested.
