Effects of H2SO4 and HCL Concentration on the Corrosion Resistance of Protected Low Carbon Steel

Abstract

Astract Investigations were carried out to study the corrosion behavior of unprotected and protected low carbon steel using carburizing and hard chrome plating in different concentrations of H 2 SO 4 and HCL solutions. Weight loss method was used for estimation the corrosion rate in the current study. The results show that protected low carbon steels samples by hard chrome plating had better corrosion resistant (less corrosion rate) than unprotected and carburized low carbon steel samples. Also, the corrosion rate increases with increasing acid concentration from (1 to 5)M. for both types of acid used. The corrosion rate of low carbon steel in acid environments indicate that the hydrochloric acid solution was more corrosive media than that of sulphuric acid solution under the same conditions.
