硫脲、硅酸盐对碳钢钝化作用的影响

The passiving effect of (NH_2)_2CS and N_2SiO_3 on carbon steel

本文利用电化学方法 ,通过碳钢在含有ZnSO4 ,Na2 HPO4 与 (NH2 ) 2 CS或Na2 SiO3 三者复配得 4mol/L的 (NH4 ) 2 CO3 溶液中的阳极极化曲线的测定 ,分析得出 :在特定的环境中 ,ZnSO4 ,Na2 HPO4 与 (NH2 ) 2 CS或Na2 SiO3 三者复配物对碳钢都有较理想的钝化作用。

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.
