摘　　要：研究了不同稀土Ce含量对AZ91D镁合金显微组织和干摩擦磨损性能的影响。通过X射线衍射(XRD)及扫描电镜(SEM)观察与分析表明,AZ91D镁合金中添加稀土Ce后,生成了杆状的稀土化合物Al4Ce。干摩擦磨损结果表明,在高载荷作用下,稀土的加入量并不能提高AZ91D镁合金的摩擦磨损性能。The effects of Ce on the microstructures and dry friction and wear properties of AZ91D magnesium alloy containing varied contents of Ce were investigated.X-ray diffraction and scanning electron microscopy were used to analyze the microstructures and wear surface morphology of the alloys.The results show that the bacillary compounds A14Ce were formed by addition rare earth Ce to AZ91D magnesium alloy.The results of the dry friction and wear illustrate that the wear properties can not be improved by addition Ce to AZ91D magnesium alloy.
