摘要
The effects of nano-ZrO2, ZrO2 fiber and sintering additives on the mechanical properties of Al2O3 ceramic composite were investigated by means of orthogonal experimental design. Meanwhile, the effect of environmental temperature on flexural strength of Al2O3 ceramic composite was tested. XRD and SEM were used to analyze the microstructure. The results showed that the content of ZrO2 fiber had the greatest effect on flexural strength and fracture toughness, followed by the content of nano-ZrO2. Nano-ZrO2 made the crystalline grains of Al2O3 smaller. ZrO2 fiber pulled out from Al2O3 matrix could consume energy of crack and increase the flexual strength and toughness of ceramic composite.
