Abstract
Pure and composite nickel deposits containing nano-Al2O3 particle (50 nm) were produced under direct current (DCED) and pulsed current electrodeposition (PCED) conditions in the presence of magnetic field (MF). The influence of MF on the co-deposition of Al2O3 particles, texture coefficient of Ni and Al2O3, crystallite size, thickness, current efficiency and hardness of the deposits were investigated systematically. PCED regime exhibited higher incorporation nano-Al2O3 percentage than those obtained under DCED condition. The electrochemical impedance spectroscopy results show several order higher Rct and lower icorr for PCED NiAl2O3 in the presence of magnetic field (MF) than that of DCED NiAl2O3 composites.
