用低压热等静压方法在1100℃下制备了HA(ZrO2)-316L不锈钢纤维非对称FGM,其中316L不锈钢纤维含量按体积比20%→15%→10%→5%呈非对称梯度变化.并通过金相显微镜、SEM、EDXA分析了材料的微观结构和微区元素含量.结果表明,HA(ZrO2)-316L不锈钢纤维非对称FGM微观上表现为316L不锈钢纤维在FGM中呈无序、均匀分布状态,316L不锈钢纤维包裹于HA(ZrO2)基体中,两者结合紧密,界面表现为部分凹凸不平,316L不锈钢纤维与HA(ZrO2)基体紧紧的咬合在一起.在FGM基体中发生了微量的韧化相Fe元素扩散,韧化相316L不锈钢纤维不发生基体相Ca、P元素的扩散,基体与韧化相均相对独立,二者之间不发生任何化学反应.随着HA含量增加,HA(ZrO2)-316L不锈钢纤维复合材料的断裂韧性和弹性模量逐渐减小,体现了FGM中各梯度层的力学性能缓和设计.HA(ZrO2)-316L不锈钢纤维FGM中,分析认为,增韧机理主要为纤维拔出增韧和层间裂纹偏转增韧.
