摘要：

SiO2-diamond composites with 65-85 mass% diamond were fabricated by spark plasma sintering at 1873 K under 130 MPa for 300 s using bimodal diamond particle size of 2 and 25 mu m in diameter. The diamond particles were coated with a SiC layer by chemical vapor deposition. The effects of diamond content on relative density, microstructure, and Vickers hardness of the SiO2-diamond composites were investigated. The SiO2-diamond composites exhibited relative density of 96%, and Vickers hardness of 36.2 +/- 3.6 GPa at 75 mass% diamond content.
