The present work studies the tribological performance of Tungsten Carbide (WC) nanoparticles reinforced epoxy polymer nanocomposites. Polymer nanocomposites are prepared by hand lay-up method. Erosive wear and hardness tests were conducted to examine the physical and wear properties of epoxy/WC nanocomposites. Addition of WC nanoparticles led to significant reduction in erosion rate. In addition to that, incorporation of WC nanoparticles enhanced the hardness of epoxy nano composites. At 2% weight of WC nano filler, nanocomposites showed better performance in erosion wear properties and also in hardness. While at 3wt% of WC filler, least performance in hardness was caused by the weak adhesive bonding between the matrix and filler. The nature of erosion wear behavior was observed. Finally worn surfaces of nanocomposites were inspected using a “scanning electron microscope (SEM)”. KeywordsEpoxy, Polymer nanocomposites, Tungsten carbide, Sand erosion, Hardness.

碳化钨填充环氧聚合物纳米复合材料的显微硬度和冲蚀磨损行为

本工作研究碳化钨（WC）纳米颗粒增强的环氧聚合物纳米复合材料的摩擦学性能。聚合物纳米复合材料通过手糊法制备。进行了磨损和硬度测试，以检查环氧/ WC纳米复合材料的物理和磨损性能。WC纳米颗粒的添加导致腐蚀速率的显着降低。除此之外，WC纳米颗粒的加入提高了环氧纳米复合材料的硬度。WC纳米填料的重量为2％时，纳米复合材料在侵蚀磨损性能和硬度方面表现出更好的性能。当WC填料的含量为3wt％时，由于基体和填料之间的弱粘合剂粘结而导致硬度性能最低。观察到腐蚀磨损行为的性质。使用“扫描电子显微镜（SEM）”检查纳米复合材料的最终磨损表面。环氧树脂，聚合物纳米复合材料，碳化钨，砂蚀，硬度。
