%X The corrosion behavior of type 45 carbon steel in polymer oil recovering sys- tem has been investigated by a simulated experiment set. The uniform corrosion, pitting and passivation of type 45 steel in HPAM and alkaline (Na,C03) mixed flooding medium were studied by potentiodynamic scanning and EIS method. The result showed that type 45 steel showed an active dissolution in HPAM solution. However, it would be changed into passiva- tion if the concentration of Na,C03 increased up to 2.Owt% in HPAM+Na2C03 mixed medi- um due to forming a compact a-Fe,03 oxide film on metal surface, but pitting emerged in lower concentration of Na2C0,(<0. 5wt %I.
