Abstract: The synthesized tungsten nanoparticles (0.5 g/l, range 40 to 150 nm) are dispersed randomly into electroless Ni-P matrix for Ni-P-W nanocomposite platings on an AISI1040 grade steel substrate (MS). The thickness of these deposits is in range of 15 to 25 micrometer. The scanning electron microscope attached in permutation of energy dispersive spectroscopy furthermore X-ray diffraction techniques were exploited to analyze surface morphology, elemental symphony and phases of platings correspondingly. The results of these studies reveal successful fusion of tungsten nanoparticles as white globules into electroless Ni-P matrix and with those as-deposited platings have amorphous structure and heated platings (400°C) have crystalline structure. Further Ni-P/Ni-P-W platings are investigated for microhardness by respective technique. The results of the studies corroborate that inclusion of tungsten nanoparticles into electroless Ni-P plating enhances the microhardness. The phase transformation initiation of amorphous nickel is headed toward nickel phosphide and crystalline nickel completely at 400°C which improved microhardness of nanocomposite Ni-P-W electro less platings.
