摘      要：Passive films formed on sensitized stainless steel in sulphuric acid solutions have been studied using photoelectrochemical techniques. The results of the photocurrent measurement indicate that the passive films on sensitized stainless steel are characterised with n-type or p-type semiconductor in different potential regions. The difference in the photoelectrochemical behaviour can be interpreted assuming that the passive film is an iron-chromium oxide solid solution associated with various hydration degrees of the Cr(III)-oxides at various potentials.
