分析研究了金属型铸造稀土锌基复合材料的力学性能和摩擦磨损性能，以及石墨和硅颗粒对稀土锌基复合材料组织的影响，指出石墨和硅颗粒与基体间的结合为机械结合。
The mechanical properties, friction and wear properties, as well as the effect of graphite and silicon particles on the microstructure of the rare earth zinc-based composites were analyzed and studied. It is pointed out that the bonding between the graphite particles and the silicon particles is mechanical bonding.
