This paper deals with the preparation and characterization of Nickel-coated Alumina ceramic particles by Electroless Plating Technique. Nanosized α-Al2O3 powders of about 50nm in diameter are used for plating. The bath for Electroless Nickel Plating is prepared with NiCl2.6H2O, C6H5NaO7.H2O, NH4Cl and NaH2PO2.H2O. A bath temperature of 85°C, pH value of 8 and stirring time of 20 min is considered to carry out the deposition. The influence of sensitization and activation under different rinsing conditions on the Nickel coating over the Surface of Nano Alumina is studied. The results of these powders are analyzed through morphology, microstructure and phase with scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffractometry (XRD) respectively.
