Comparative Study of Corrosion Inhibition In Carbon Steel Using Non Ionic Surfactants In Acidic Medium
Abstract: The use of surfactants is one of the numerous ways of protecting a metallic surface from electrochemical oxidation or corrosion. The amphiphilic nature of these surfactants leads to the formation of a protective layer on the metallic surface, effectively minimizing the area of contact between the fluids and the metal, thus inhibiting corrosion. Cationic surfactant like CTAB (Cetyltrimethylammonium bromide) has been most commonly used as a corrosion inhibitor, but since …
