英文摘要	An investigation on the growth of passive film on 304 stainless steel by using alternating voltage (A.V.) passivation was carried out by electrochemical impedance spectroscopy (EIS), coulometry measurement and atomic force microscopy (AFM). EIS was performed on 304 stainless steel electrode, which is covered by A.V. passive film, to identify the formation of pore as a function of higher potential parts (Eh) in alternating square wave electric field. Coulomb-time curves were measured during the growth of passive film on different conditions. A new concept, probability of pore formation, which describes the behaviour of the pores during the growth of film, was presented. Results indicate that the growth mechanism of A.V. passive film is different from that of D.C. passive film, which makes the AV. passive films have a faster growth rate. Coulomb-time curves and AFM analysis confirmed the growth mechanism of A.V. passive film.
