| 摘 要： | 研究了快速热压烧结和放电等离子快速烧结（ＳＰＳ）制备纳米Ｙ－ＴＺＰ材料，利用快速热压烧结和ＳＰＳ快速烧结，可在烧结温度为１２００℃，保温９￣１０ｍｉｎ条件下，制得相对密度超过９９％的Ｙ－ＴＺＰ材料，研究发现，虽然快速热压烧结和ＳＰＳ烧结都可使Ｙ－ＴＺＰ在相同温度下的密度高于普通热压烧结，但两种快速烧结所得Ｙ－ＴＺＰ的晶粒孝大于无压烧结所得；另外，快速热压结所得样品的结构不够均匀，而ＳＰＳ烧结样品的

| Abstract: | Ultrafine 3Y-TZP materials were fabricated by the rapid hot-pressing and SPS(Spark Plasma Sintering). It was found that although the relative densities of the Y-TZP sintered by the two kinds of rapid rate sintering methods were higher than that of sintered by ordinary hot-pressing at the similar sintering temperature, the grain sizes were larger than that obtained by pressureless sintering; On the other hand, the structure of the samples sintered by SPS was much homogeneous than that sintered by rapid hot-pressing. The reasons of those phenomena were also discussed. By choosing appropriate condition, ultrafine 3Y-TZP materials with a relative density of 99% could be gotten by both the two kinds of rapid rate sintering. |
