%X The corrosion of A3 carbon steel induced by micrococcus was studied using polarization curve and AC-impedance techniques.The results indicated:(1) When micrococcus existed,carbon steel corrosion was accelerated by a loose and heterogeneous biofilm formed on its surfaces;(2) R po and C c values were close after two days and four days immersion respectively in solutions with micrococcus,which indicated that the metabolization of bacteria became stable,and the biofilms under two conditions were tend to be ripe and accordant;(3) The equivalent circuits for situations without or with bacteria were proposed respectively,and the parameters in circuits were also calculated;and (4) Corrosion reaction impedance with micrococcus showed dispersion effect.
