山东省冶金科学研究院最近向社会推出稀土锌基复合材料应用研究成果。据介绍，稀土锌基复合材料是利用稀土锌基合金与具有自润性能和耐磨性能的非金属粒子（石墨、硅）采用特定复合熔制工艺和金属型重力铸法制成。从而获得在稀土锌基合金基体中较均匀地分布着粉粒状的石墨、硅 Shandong Academy of Metallurgical Science recently introduced to the community of rare earth zinc-based composite materials applied research results. According to reports, the rare earth-based zinc-based composite material is the use of rare earth-based zinc alloy with self-lubricating properties and wear resistance of non-metallic particles (graphite, silicon) using a specific composite melting process and metal gravity casting method. Thereby obtaining graphite and silicon which are more evenly distributed in the rare earth zinc-based alloy matrix
