摘要
利用硬度压痕法测定了氧化镁部分稳定氧化锆（ＭｇＯ－ＰＳＺ）陶瓷材料的断裂韧性Ｋ＿（１ｃ）。研究了在不同热处理条件下ＭｇＯ－ＰＳＺ断裂韧性的变化，发现在１４００℃和１１００℃下分级热处理后，ＭｇＯ－ＰＳＺ的断裂韧性显著提高。研究分析了ＭｇＯ－ＰＳＺ的韧性与显微组织的关系。
The fracture toughness(K_(1,c) of MgO partially stabilized zirconia ceramics is measured by the hardness indentation method in this paper.The dependence of the fracture toughness of MgO-PSZ on heat treatment conditions is studied.K_(1c) of MgO-PSZ can be greatly improved by means of two-step heat treatment at 1400℃ and 1100℃.The relationship between the fracture toughness and phase portion of the material is discussed.
