摘要：

采用粉末冶金法经1000℃烧结制备了可加工硅碱钙石微晶玻璃/金属铜功能梯度复合材料(functionally gradient materials,FGM),其中金属含量(质量分数)为0,20%,40%,60%,80%和100%,呈非对称梯度变化。通过金相显微镜、扫描电镜、X射线电子能谱等分析了材料的微观结构和微区元素含量,用万能材料试验机测试了复合材料的弯曲强度。结果表明:硅碱钙石微晶玻璃/金属FGM的结构呈宏观不均匀且微观连续变化,微晶玻璃相与金属粉末相结合紧密,两相均相对独立,两者之间没有发生化学反应;随着金属粉末含量的增加,硅碱钙石微晶玻璃/金属功能梯度复合材料中各梯度层的热膨胀系数和力学性能逐渐变化。

Machinable canasite glass-ceramics and metal Cu functionally gradient materials(FGM)were successfully prepared by sintering at 1 000 ℃ by the powder metallurgic process,where the asymmetrical stepwise change of mass fraction of metal powderof 0,20%,40%,60%,80% and 100%.Metallographic microscopy,scanning electron microscopy and energy dispersive X-ray spectroscopy analysis were carried out to examine the microstructure and element contents of the FGM,and a multi functional material testing machine was used to measure the flexural strength of the FGM.The results show that this FGM displays the microstructural characteristics of macroscopic inhomogeneity and microscopic continuity.The glass-ceramics phase and the metal phase are closely integrated,but the two phases are relatively independent and no chemical reaction was observed between them.With the addition of the metal powders,the thermal expansion coefficient and the mechanical properties of each layer in the canasite glass-ceramic and metal FGM also changed gradually wisely.
