【Abstract】 This text describes the anode polarization curve obtained from the carbon steel test in the 4 mol/L (NH 4) 2CO 3 solution prepared by ZnSO 4,Na 2HPO 4 and(NH 2) 2CS or Na 2SiO 3 with the electrochemistry method.From the analysis,we know that the solution prepared by ZnSO 4,Na 2HPO 4 and(NH 2) 2CS or Na 2SiO 3 has a good passiving effect on the carbon steel under certain conditions.更多还原
