Preparation and Study of Novel Nano-Composite Coatings on the Surface of Plastic Moulds
Compared with ordinary coatings, nano-composite coating usually has a higher hardness and better wear and corrosion resistance. As coating materials, the nano-CeO2/Zn composites were prepared by nano-CeO2 and Zn powder. The microstructure was investigated by XRD and FESEM. The corrosion resistance and hardness of nano-CeO2/Zn composites with different amount of nano-CeO2 were comparatively studied. The results show that the metal corrosion resistance, hardness and density of the composites may be improved significantly by addition of nano-CeO2, and the optimal amount of nano-CeO2 is 1%.
