| 摘 要： | 本文采用放电等离子烧结技术（ＳＰＳ）快速烧结结纳米３Ｙ－ＴＺＰ材料，利用ＳＰＳ技术快速烧结，可制备出完整、致密的３Ｙ－ＴＺＰ材料，在烧结温度为１３００℃，保温３ｍｉｎ条件下，相对密度达９８．２％，晶粒仅１００￣１３０ｎｍ，研究发现，材料的密度随烧结温度的变化趋势与一般快速烧结有明显区别；材料的晶粒随烧结温度的提高而长大，但长大幅度小于其他一些烧结方法所得的３Ｙ－ＴＺＰ材料，本研究对这些现象进行了理

| Abstract: | The SPS(Spark Plasma Sintering) process was used to prepare ultrafine 3Y-TZP materials. It was found that dense samples(>2g) without crack can be fabricated by SPS process. The density of the samples increases with the rising of sintering temperature and soaking time. The grain size of the sample also increases with the rising of sintering temperature but the increasing speed will be slow compared with some other sintering methods. The mechanism of these phenomena was investigated. By choosing appropriate conditions, ultrafine 3Y-TZP materials with grain size of about 100~130nm and relative density of 98.2% can be made. |
