Influence of CeO2 nanoparticles on the corrosion behavior of electrodeposited Ni coatings
Abstract: Nickel-Ceria (Ni-CeO2) nanocomposite coatings were developed on mild steel (MS) substrate using electrodeposition method. The codeposition of the nanoparticles was achieved from the optimized Ni plating bath loaded with CeO2 nanoparticles (particle size <20 nm). Ni and Ni-CeO2 coatings were achieved at a wide current density (c.d.) range from 1.0 to 5.0 A/dm2 under optimal conditions, and their corrosion protection efficacy was examined in 5% NaCl medium. The material property …

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 …
