Preparation of CeO2 Particle Reinforced Aluminum Matrix Composites Based on FSP Technology

采用搅拌摩擦加工技术研究制备了CeO2颗粒增强5083铝基复合材料,研究了加工道次对材料微观组织、显微硬度和磨损体积的影响。研究结果表明:CeO2颗粒在基体中的分散程度随着加工道次的增加而增强;添加CeO2颗粒可以提高材料的硬度和耐磨性,材料的显微硬度随着加工道次的增加而增加,3道次加工后的磨损体积最小。

CeO2 particle reinforced 5083 aluminum-based composites were prepared by friction stir processing technology,and the effects of processing passes on the microstructure,microhardness,and wear volume of the material were studied.The results show that the dispersion of CeO2 particles in the matrix increases with the number of processing passes.Adding CeO2 particles can improve the hardness and abrasion resistance of the material.The microhardness of the material increases with the increase of processing passes,and the wear volume after 3 passes of processing is the smallest.
