Abstract Numerous reports have elucidated that synthesis of graphene (Gr)-reinforced metal matrix composites is difficult by conventional manufacturing techniques because Gr exhibits a large surface area as well as high tendency to agglomerate. Consequently, herein, a Gr/316L stainless-steel composite was synthesized through an alternate process, namely: powder-bed fusion. The effects of the Gr content on the hardness and wear behavior of the prepared composite were investigated. The hardness of prepared composite increased by up to 25%, and due to the solid lubrication property of Gr, wear rate of prepared composite also reduced significantly. The results of this study indicate that Gr is an ideal reinforcement for a stainless-steel matrix composite, as it improves the wear performance and hardness.

激光选区熔化制备石墨烯增强316L不锈钢复合材料的摩擦学行为

摘要 大量报道表明，石墨烯 (Gr) 增强金属基复合材料的合成很难通过常规制造技术进行，因为 Gr 具有较大的表面积和高团聚倾向。因此，在本文中，通过替代工艺合成了 Gr/316L 不锈钢复合材料，即：粉末床融合。研究了 Gr 含量对制备的复合材料的硬度和磨损行为的影响。制备的复合材料的硬度提高了25%，并且由于Gr的固体润滑性能，制备的复合材料的磨损率也显着降低。这项研究的结果表明，Gr 是不锈钢基复合材料的理想增强材料，因为它提高了耐磨性能和硬度。
