摘要：
The effects of calcium hexaluminate (CA(6)) on the microstructure and mechanical properties of zirconia-toughened-alumina ceramic were investigated. Zirconia-toughened-alumina (ZTA) composites which have different additions of calcium hexaluminate were successfully fabricated by pressureless sintering at 1600 degrees C for 3 h. The results showed that the bending strength of the composites improved with the increase of CaAl12O19 addition while the fracture toughness declined. The ZTA composite incorporated with CA(6) showed better abrasion resistance property in long cycling period (>640 cycles) than that without CA(6).
