摘要: 运用真空热压烧结法制备石墨烯纳米片(GNP)增强纯钛轻质结构材料。采用光学显微镜、扫描电镜和透射电镜等手段对制备得到的粉体和块状样品的微观组织结构进行了分析。对添加不同石墨烯纳米片含量的烧结样品进行了密度测试和拉伸测试。研究工作集中关注了GNPs在钛基体中的分散和GNP与钛基体的界面结合情况。结果表明,GNP与钛基体的界面分界清晰,形成Ti/TiCx/GNP连续结构,界面处有少量TiCx生成外,大部分GNP依然以其纳米结构存在。Abstract: Graphene nanoplatelets(GNP) reinforced pure titanium lightweight structural materials were prepared by vacuum hot pressing sintering method.The microstructure of the powder and block samples were analyzed by optical microscope,scanning electron microscope and transmission electron microscope.The density test and tensile test were carried out on sintered samples with different content of graphene nanosheets.The research focuses on the dispersion of GNPs in titanium matrix and the interfacial bonding between GNP and titanium matrix.The results show that the interface between GNP and titanium matrix is clearly demarcated,forming a Ti/TiCx/GNP continuous structure.Most GNP still exists in its nanostructure except for a small amount of TiCx generated at the interface.
