| description | Roughening is one of the main problems in the electrodeposition process and numerous studies have been carried out to reduce it. One of the methods of tackling this problem is by using the magnetoelectrodeposition (MED). MED plays a vital role in the electrodeposition process to synthesize metal alloys, thin films, and microelectronics devices. However, this MED technology has not been widely investigated. This work is aimed to study the limiting current under magnetic field effects (MFE) on an electrodeposition system of cobalt, tin and lead which represents ferromagnetic, paramagnetic and diamagnetic species respectively. Boric acid, gluconate and sorbitol are used in this study as additives electrolyte of cobalt, tin and lead MED systems, respectively. The limiting current is very important because it will affect the optimum mass transport achieved in the electrodeposition process. Here, the MFE on limiting current electrodeposition are investigated in terms of variations in the electrode area (A), the concentration of the electro active species (CBulk), the diffusion coefficient of the electroactive species (D), the kinematic viscosity of the electrolyte (v), magnetic strength (B) and the number of electrons involved in the redox process (n). MFE with flux density of up to 0.3 T on cobalt, tin and lead electrodeposition in the presence of additive electrolyte were investigated. |
