| Abstract: | The Ni-nano Al2O3 composite plating was prepared on SUS304 stainless steel. The distribution of Al2O3 particles in the composite plating was examined. The proper amount of particles in the solution, current density as well as stirring speed for electroplating was then determined. Scanning electron microscope (SEM) and X-ray diffraction (XRD) were used to characterize the microstructure, composition and phase constituent of the plating. The results showed that the Ni-Al2O3 composite plating was very compact with small grain size, good adhesive to the substrate and excellent corrosion resistance. Furthermore the high-temperature oxidation resistance of the composite plating was higher than that of the Ni plating. |
