Research of the Forming Technologies of Nano-ceramic

Traditional ceramic materials are renowned for their merits of high temperature resistance, corrosion resistance, high strength and high rigidity, yet their further development is always hindered by their.brittleness. The problem has been overcome by nano-ceramic materials, which boast the qualities of high toughness and low-temperature superplasticity. This paper analyzes the research status of the traditional forming technologies of nano-ceramic and their merits and defects, expounds on the developmental trends of these forming technologies, and points out that there＇s a promising prospect in applying the laser forming technology to the production of high-performance nano-ceramic parts.
