Al2O3-TiC composite materials for cutting tool have been produced by the powder metallurgy process such as hot pressing and HIP. However, there are still problems in fabricating three dimensional complex shaped components. Powder injection molding (PIM) process may solve those problems because of the near net shape forming with complexity.
This study has been performed to determine the production feasibility of Al2O3-30mass%TiC composite materials by PIM process, and the mechanical properties and microstructures of them. Especially, the effects of binder loading and debinding and sintering conditions on the mechanical properties (hardness and transverse rupture strength) were investigated in detail. Finally, high performance Al2O3-30mass%TiC composite materials were obtained by the optimized PIM process.
