O knihe

This book titled 'Alloy Coatings for Corrosion Protection and Electrocatalysis' is a comprehensive approach for improving the corrosion resistance and electrocatalytic activity of Ni-W alloy coatings. The corrosion resistance of monolayer alloy coatings was improved to many folds of its magnitude through multilayer approach by depositing in layers, having alternatively different composition. Further, the benefit of magnetoelectrodeposition (MED) has been explored for improving the coating characteristics of Ni-W alloy. The conditions of MED have been optimized for maximizing the corrosion protection efficacy of Ni-W alloy coatings. A significant change in the deposit characters has been observed due to increase in the limiting current density (iL), explained by the magnetohydrodynamic (MHD) effect. The electrocatalytic activity of the alloy coatings towards hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) were tested using electrochemical methods. The corrosion resistance and electrocatalytic activity of Ni-W alloy coatings developed using different methods were compared in relation to their composition, surface morphology and phase structure.
