Abstract
Electrochemical coating processes are significantly affected by applied magnetic fields due to the generation
of electromagnetic forces. The present research work has been undertaken to study the effect of coating parameters
such as current density and alumina concentration on the characteristics of Ni-Al2O3 composite coating under static
magnetic field. Ni-Al2O3 composite coating was applied on a mild steel substrate using conventional Watts solution
containing Al2O3 particles with and without magnetic field. The coating microstructure and Al2O3 particle density in
the coating layer were examined by scanning electron microscopy (SEM). It was found that the applied magnetic field
made the coating structure finer and leads to the increases of the particle content in the coating. However, the results
confirmed that the magnetic forces inversely affected the particle density in the coating at higher current density than
that of normal coating process.
