摘要
利用原位反应同喷射沉积工艺相结合的方法制备了TiB2/Zn-30Al-1Cu复合材料。采用光学显微镜(OM)、扫描电镜(SEM)对该复合材料的组织进行观察,并对其进行了X射线衍射测试分析。结果表明,在合理的喷射沉积工艺参数下,TiB2颗粒在基体材料中均匀分布并且尺寸小于2μm;原位反应TiB2颗粒的引入使得该复合材料的组织细化,初生富铝相α'相较多,呈细小的颗粒状形态且α'相尺寸小于2μm。
An innovative spray deposition technique was applied to produce in-situ TiB2/Zn-30Al-1Cu composite. The microstructure of the composite was studied by using optical microscopy, scanning electron microscopy and X-ray diffraction. Both theoretical and experimental results have shown that TiB2 particulates appear in the microstructure. The results show that TiB2 particles distribute in Zn-30Al-1Cu matrix uniformly, and the TiB2 particles are about 2 μm in size. Moreover, the presence of TiB2 particles can lead to the refinement of the microstructttre of matrix, and the increase of α＇ phase with less 2 μm size in the composite.
