为探讨颗粒增强低熔点金属基复合材料的制备工艺和性能，扩大锌合金的应用范围，本项工作采用旋涡搅拌法制备了ＳｉＣｐ／Ｚｎ基复合材料，并讨论了搅拌工艺参数、增强颗粒表面处理对复合效果的影响。显微组织观察表明：ＳｉＣｐ分布均匀程度取决于颗粒的表面处理以及复合工艺参数的控制。ＳｉＣｐ经高温焙烧后，其表面获得一层稳定的ＳｉＯ２，从而有利于改善ＳｉＣｐ与基体锌合金的浸润性能。在基体中加入Ｍｇ等金属粉末，对于ＳｉＣｐ与基体的复合效果以及它的分布状态都起着良好的作用。此外，ＳｉＣｐ的加入速度，ＳｉＣｐ的粒径对复合效果也有较大影响。
In order to explore the preparation process and properties of particle reinforced low melting point metal matrix composites and to expand the application range of zinc alloy, SiCp / Zn matrix composites were prepared by vortex stirring in this work. The effects of stirring parameters, particle surface treatment Effect on compounding effect. Microstructure observation shows that the uniformity of SiCp distribution depends on the particle surface treatment and the control of composite process parameters. SiCp calcined at high temperature, the surface of a layer of stable SiO2, which is conducive to improving the infiltration of SiCp and the matrix of zinc alloy. Addition of metal powder such as Mg into the matrix plays a good role for the composite effect of SiCp and the matrix as well as its distribution state. In addition, the addition rate of SiCp, SiCp particle size has a greater impact on the composite effect.
