摘要：

The inhibitor effect of some surfactants in the series of 2-(alkyl(CnH2n+1)dimethylammonio)alkanol bromides on the corrosion of iron in acid chloride medium have been investigated by steady-state electrochemical and gravimetric methods. Results obtained show that these compounds are very good cathodic inhibitors and act on the cathodic hydrogen reaction evolution without modifying its mechanism. High inhibition efficiencies are observed around their critical micellar concentrations and the inhibition efficiency increases with the number of carbon atoms in the chain length.
