MgO添加量对95瓷耐磨性的影响

Effect of MgO Content on Wear resistent Performance of Alumina Ceramics

适量的 Ｍｇ Ｏ 可以改善９５ 瓷的耐磨性。通过一系列的实验得知，当加入 Ｍｇ Ｏ 量在０２５％ 、常压下、１ ６４０℃保温２ｈ 可以制得耐磨性很好的 Ａｌ２ Ｏ３ 瓷。这种提高９５ 瓷耐磨性的方法经济实惠，具有非常重要的实用意义。

The wear resistent performance of the 95% alumina ceramics is increased with the addition of optimal amount of MgO.The optimal wear resistent performance of the 95% alumina ceramics is obtained when MgO content is 0.25%,and the specimen is sintered at 1 640℃ and maintained 2h.The addition of MgO to increase the wear resistent performance of 95% alumina ceramics is a very important and economic method.
