A 0.3wt% graphene nanoplatelets (GNPs) reinforced 7075 aluminum alloy matrix (7075 Al) composite was fabricated by spark plasma sintering and its strength and wear resistance were investigated. The microstructures of the internal structure, the friction surface, and the wear debris were characterized by scanning electron microscopy, X-ray diffraction, and Raman spectroscopy. Compared with the original 7075 aluminum alloy, the hardness and elastic modulus of the 7075 Al/GNPs composite were found to have increased by 29% and 36%, respectively. The results of tribological experiments indicated that the composite also exhibited a lower wear rate than the original 7075 aluminum alloy.

放电等离子体烧结石墨烯纳米片增强7075铝合金复合材料的力学性能

通过火花等离子体烧结制备了0.3wt%的石墨烯纳米片增强了7075铝合金基体(7075 Al)复合材料,并对其强度和耐磨性进行了研究。内部结构,摩擦表面和磨损碎片的微观结构通过扫描电子显微镜,X射线衍射和拉曼光谱进行表征。与原始的7075铝合金相比,发现7075 Al / GNPs复合材料的硬度和弹性模量分别增加了29%和36%。摩擦学实验的结果表明,该复合材料的磨损率也低于原始的7075铝合金。
