| Abstract: | The corrosion behavior of N80 steel in H 2S solution with various concentration of CTAB is studied by means of stable polarization. And the change of the Nyquist plots is obtained when CTAB is added to the acid solution with H 2S. The results show that adding CTAB into the acid solution with H 2S can increase the reaction resistance of N80 steel, decrease the capacitance of interfacial double electrode layer, and restrain the anodic reaction of corrosion, then bate the corrosion rate of N80 steel effectively. |
