用极化曲线和交流阻抗技术测定了钢在含不同浓度甲基红的 1.0 mol/ L HCl和 0 .5 m ol/ L H2 SO4+0 .5 mol/ L Na2 SO4溶液中的腐蚀速率和传递电阻 ,求出了缓蚀效率。结果表明 ,甲基红无论是在 HCl溶液中或是在0 .5 mol/ L H2 SO4+0 .5 mol/ L Na2 SO4溶液中都有较高的缓蚀效率
The corrosion rate and transfer of steel in 1.0 mol / L HCl and 0.05 mol / L H2 SO4 + 0.5 mol / L Na2 SO4 solution with different concentrations of methyl red were measured by polarization curves and AC impedance techniques Resistance, obtained inhibition efficiency. The results showed that methyl red showed high corrosion inhibition efficiency both in HCl solution or in 0.5 mol / L H2 SO4 + 0.5 mol / L Na2SO4 solution
