| Abstract: | The mechanical performance of Al 2O 3 TiB 2 ZrO 2 compound ceramic cutters and their wear characteristics under the continuous and discontinuous cutting condition are experimental investigated. The results show that the toughness and strength of ceramic cutters are improved by adding TiB 2 and ZrO 2 particles into Al 2O 3 ceramic material, but without obvious decrease on the hardness of the cutters. So that ZrO 2 TiO 2 Al 2O 3 compound ceramic cutters show an excellent mechanical performance and wearing resistance. |
