Microstructure Study and Morphology of Ni / Nano Al2O3 Composite Coating Synthesied by Electroless Plating

The electroless deposition method was used to prepare Ni-based nanocomposite coatings, this approach represents an alternate way of having coatings on the different substrates. Most previous literatures subject and work deals with a study effect process conditions and, Bath composition microstructure at macroscale Ni-Al2O3 composite coatings. Though, step structure bath are little, present aims hard ceramic Al2O3 nanoparticles concentrations (0.0, 0.5, 1.0, 2, 4) g/L, phase structure, morphology coating, in order enhance mechanical, plysical chemical properties coating. In paper, An X-Ray diffraction method, spectroscopy (EDS), energy dispersive, scanning electron microscope (SEM) were studied morphological nanocomposition is evident from EDS that coating consists Ni Al2O3. micrograph showed A flat smooth surface deposited Uniform distribution alumina within Ni-Matrix. And XRD crystalline Ni-
