用线性极化技术测量了不同温度(10℃～60℃)下10~#钢在1.0NH_2SO_4和添加缓蚀剂硫脲及其衍生物中的腐蚀速度.并根据反应活化能的大小探讨了它们的反应机理,所得结果与动态极化曲线法进行了比较. The corrosion rates of 10 # steel in 1.0NH_2SO_4 and added corrosion inhibitor thiourea and their derivatives at different temperatures (10 ℃ ~ 60 ℃) were measured by linear polarization technique, and their activation energies were discussed The reaction mechanism was compared with the dynamic polarization curve method.
