| Abstract: | The relation between SiO2 content in coating and cathodic current density was studied in Watts solu-tion, along with the effects of technological condition and parameters on the composite coating had also been discussed including pH value, stirring speed, current density, particle concentration and additives. The optimal bath composi-tion and technological parameters were established. The appearance and components of Ni-SiO2 coating were observed and analyzed by SEM. Experimental results showed that the crystal-refined agent could improve the appearance of composite coating, and the amount of SiO2 was about 10 wt% - 20 wt% in the Ni-SiO2 coating. The appearances of coating were uniform and fine with metallic luster. |
