Abstract:The nano-composite powders of CeO2/Zn were prepared with high energy ball milling and the nano-composite materials of CeO2/Zn were fabricated with vacuum sintering powder metallurgy. Meanwhile, the composite and structure were analyzed by the means of XRD and FESEM. From the comparison of different nano-CeO2 contents composites, the best corrosion resistance and hardness, and the optimum content of nano-CeO2 were achieved. The result shows that corrosion resistance, hardness and uniformity of metal structure can be improved significantly with nano-CeO2; at the same time, the optimal corrosion resistance, hardness and microstructure are obtained when the mass fraction of nano-CeO2 is 1%.

 

Key words: high energy ball milling; CeO2; nanocomposite; corrosion resistance; hardness
