| 摘 要： | 石墨烯拥有许多优异的性能，这些性能使石墨烯有望成为金属基复合材料的理想增强相。采用激光烧结的方法制备了石墨烯-铜纳米复合材料。X射线衍射（XRD）和Raman光谱测试结果表明，石墨烯存在于激光烧结所制备的纳米复合材料中。显微硬度测试结果显示，石墨烯的添加使得石墨烯-铜纳米复合材料的硬度比激光烧结纯铜的硬度提高了约22%。用电化学极化法研究了激光烧结的石墨烯-铜纳米复合材料和纯铜在3.5%（质量分数）NaCl 溶液中的腐蚀行为，石墨烯-铜纳米复合材料的腐蚀电位比激光烧结纯铜的腐蚀电位略有降低，腐蚀电流也有所降低，说明其耐腐蚀性能较激光烧结纯铜略好。

| Abstract: | Graphene is a fascinating material and it has many exceptional properties. The outstanding mechanical properties make it an ideal reinforcement material for metal matrix composites (MMCs). In this work, graphene reinforced copper nanocomposites were successfully prepared by laser sintering. The composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy. It was proved by XRD patterns and Raman spectrum that graphene existed in the laser sintering composites. The Vickers hardness was measured; compared with laser sintered pure copper, a 22% increase in Vickers hardness value was obtained. The corrosion behaviors of laser sintered pure copper and graphene-copper composites in 3.5% NaCl solution were studied by electrochemical polarization method. The result shows that the corrosion resistance of graphene-copper composites is a little bit better than that of pure copper. |
