用稳态极化法、阳极动电位快速扫描法和交流阻抗法研究了 N80#钢在含H2SO3酸性溶液中的腐蚀行为.结果表明：酸性溶液中H2SO3的加入， 一方面因增大了溶液的酸度而促进N80#钢的腐蚀，另一方面因一种新的吸附性中间产物的 生成而加快腐蚀.当溶液中没有H2SO3时，N80#钢腐蚀反应阳极过程生成的吸附性中间 产物是Fe(OH)ad，而加入H2SO3后，则生成另一种吸附性中间产物Fe(HSO3 )ad.
The behavior of N80# steel in acid solution at va rious pH values and with various CH2SO3 was studied by means of stable polarization,anodic linear potential sweep and a.c.impedance.The result showed that the addition of H2SO3 could increase the corrosion rate of N80# steel for two reasons;one is the decrease of solution's pH value,the other is the pro duction of an new mid adsorptive matter.The adsorption intermediate product was F e(OH)ad in process of the corrosion reaction of N80# steel in HAc-NaAc wit hout H2SO3.When H2SO3 was added to the acid solution,the adsorptive inte rmediate product was Fe(HSO3)ad.
