STUDIES ON STRUCTURE OF TRIPHENYL PHOSPHITE FILM FORMED ON THE SURFACE OF A3 STEEL

摘要

Micromorphology analysis by SEM is performed on the film of triphenyl phosphite formed on A3 steel. The results show that the film is three-dimensional. It is confirmed by XPS and IR technique that complex compound is formed between triphenyl phosphite and ferro-ferric ions. Based on the results, a possible structure of the complex compound is proposed.
