| Abstract: | The Pkotoeleetrochemical behavior of the passive film on 18-8 austenitic stainless steel in pH=8.4 borate solution has been studied. The photoelectroche,nical behavior of passive film formed on 18-8 stainless steel is compared to that formed on Fe, Ni, Cr and Fe-Cr alloy. Results indicate that the passive film on 18-8 stainless is composed of the solid solution of Fe_2O_ and Cr_2O_3. The film shows noncrystalline n-type conductor behavier. Its fiat band potential lies at -0.30V (SCE) and bandgap value is 1.geV. |
