A study has been made of the influence of various surfactants on the passivity breakdown of stainless steels and dissolution rates of iron and common steels in hydrochloric acid. A potentiodynamic method of analysis was employed to determine anodic polarization curves for iron and various steels with and without surfactants present. It was found that sodium lauryl sulfate stimulated corrosive effects, while sodium secondary alkylsulfate and alkylben-zenesulfonate displayed inhibitive qualities.
