以石墨烯为增强体,进行了体育器材用石墨烯镁基复合材料的制备,并进行了显微组织、物相组成、力学性能和耐磨损性能的测试。结果表明:该复合材料由Mg相和石墨烯相组成,与商用AZ31镁合金相比,石墨烯镁基复合材料的-20℃的抗拉强度从104MPa增加至527MPa,20℃的抗拉强度从262MPa增加至538MPa,300℃的抗拉强度从83 MPa增加至515 MPa,20℃磨损体积减小89%,150℃磨损体积减小了90%,350℃磨损体积减小了91%。
Graphene was used as reinforcement to prepare graphene - based magnesium composite for sports equipment. The microstructure, phase composition, mechanical properties and wear resistance were tested. The results show that the composite material consists of Mg phase and graphene phase. Compared with the commercial AZ31 magnesium alloy, the tensile strength at -20 ℃ of the magnesium matrix composites increases from 104MPa to 527MPa. The tensile strength at 20 ℃ The tensile strength at 300 ℃ increased from 83 MPa to 515 MPa, the wear volume decreased by 89% at 20 ℃, the wear volume decreased by 90% at 150 ℃, and the wear volume decreased by 91% at 350 ℃.
