摘要：
The complex-shaped ceramic tools were efficiently prepared by microwave sintering. The effects of loading mode of samples on distribution of microwave electric field and temperature field were studied by simulation, and the influences of different loading modes on relative density, mechanics properties and microstructure of samples were studied by experiments. Cutting performances of the complex-shaped ceramic tools were also investigated. The results show that when samples are placed horizontally and at the center of the microwave sintering cavity, the electric fields are uniform and the temperature differences are small, that is beneficial to reach full density simultaneously for several samples. The complex-shaped Al2O3/SiC composite ceramic tools prepared by microwave sintering have the integrated cutting edge and show better cutting performance. Compared with the traditional flat rake face ceramic tools, the material removal of complex-shaped ceramic tools are increased 2 times and the machined surface roughness is decreased by about 33%. "Structure-performance" integrated manufacturing technology of complex-shaped ceramic tools based on microwave sintering has broad application prospects. © 2022, China Mechanical Engineering Magazine Office.
