采用电泳沉积法在丙酮悬浮液中制备了SiC/TiC层状陶瓷复合材料。在相同的沉积电压和固体含量下，SiC的生长速率几乎是TiC的两倍。研究了无压烧结和放电等离子烧结（SPS）工艺对复合材料的烧结性能。无烧结添加剂的复合材料中的SiC即使在2000°C下也不能使用无压烧结致密化。而SPS在1800°C和35 MPa条件下可使SiC/TiC复合材料致密化。SPS样品的相对密度为98.9%。
SiC/TiC laminar ceramic composites were fabricated using electrophoretic deposition (EPD) from acetone-based suspensions. The growth rate of the SiC was almost twice that of the TiC at the same deposition voltage and solids loading. Pressureless sintering and spark plasma sintering (SPS) of the composites were investigated. SiC in the composites without sintering additives could not be densified using pressureless sintering, even at 2000°C. SPS, however, could densify the SiC/TiC composites at 1800°C and 35 MPa. The relative density of the SPS sample was 98.9%.
