Abstract
Ni P Al2O3 nano-composite coatings were successfully fabricated on a P20 plastic die steel surface by electroless plating process containing sulfate nickel, sodium hypophosphate and suspended Al2O3 nanoparticles. The pH value and temperature of the electroless bath were 4.5 and 87§C, respectively. The coating was characterized for its microstructure, morphology, microhardness and corrosion resistance. Surface analysis using a field emission scanning electron microscopy (FESEM) showed that the dispersible Al2O3 nanoparticles were co-deposited with electroless Ni P coating onto substrates, the incorporation in Ni P matrix of Al2O3 nanoparticles increases the nodularity of composite coatings. The crystallinity, phases and element distribution of coating were analyzed by X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). It was evident that the X-ray diffraction pattern of the composite coating is similar to that of nanoparticle free coating, both coatings have amorphous structures.
