Abstract Wear characteristics modified on high functionality tribo poly-ether-ether-ketone (PEEK) composite fabricated through the spatial distribution of bamboo Carbon NanoTube (B-CNT) with incrementally blended networks of sub-micron high thermal conductivity synthetic diamond (SD) particles were studied. The composites were developed by the hot press sintering route and were characterized for their mechanical, thermal stability, chemical state, and tribological properties. On the addition of reinforcement particles, the hardness of the composite was increased by 25%, and thermal stability improved by about 25 °C due to the strengthening effect of diamond particles. FTIR reveals the existence of the chemical compatibility of reinforcements in the matrix. XRD results reveal that the addition of reinforcements in the matrix does not alter the structure of PEEK. Wear characteristics of PEEK composite were investigated by varying applied pressures. The coefficient of friction reduced to 30% for 0.5%SD & 0.75%B-CNT sample, and the specific wear rate was reduced to 39% for 1%SD & 1%B-CNT sample compared to neat PEEK, at maximum loading condition. The coefficient of friction and specific wear rate were reduced to a larger extent due to transfer film consisting of ferric oxide film confirmed by XPS oxygen region peak 531.85 eV and distorted polymer rings was confirmed by Raman spectroscopy.

竹碳纳米管 (B-CNT)-peek 复合材料与亚微米合成金刚石颗粒增量混合的磨损和摩擦膜表征

摘要 通过竹碳纳米管 (B-CNT) 与亚微米高导热合成金刚石 (SD) 颗粒的增量混合网络制备的高功能摩擦聚醚醚酮 (PEEK) 复合材料的磨损特性被研究。复合材料是通过热压烧结工艺开发的，并对其机械、热稳定性、化学状态和摩擦学性能进行了表征。添加增强颗粒后，由于金刚石颗粒的强化作用，复合材料的硬度提高了25%，热稳定性提高了约25°C。FTIR 揭示了基体中增强材料的化学相容性的存在。XRD 结果表明，在基体中添加增强剂不会改变 PEEK 的结构。通过不同的施加压力研究了 PEEK 复合材料的磨损特性。在最大负载条件下，与纯 PEEK 相比，0.5%SD 和 0.75%B-CNT 样品的摩擦系数降低至 30%，1%SD 和 1%B-CNT 样品的比磨损率降低至 39% . 由于由 XPS 氧区峰值 531.85 eV 证实的氧化铁膜组成的转移膜和拉曼光谱证实了扭曲的聚合物环，摩擦系数和比磨损率降低了更大的程度。在最大负载条件下，与纯 PEEK 相比，1%SD 和 1%B-CNT 样品的比磨损率降低至 39%。由于由 XPS 氧区峰值 531.85 eV 证实的氧化铁膜组成的转移膜和拉曼光谱证实了扭曲的聚合物环，摩擦系数和比磨损率降低了更大的程度。在最大负载条件下，与纯 PEEK 相比，1%SD 和 1%B-CNT 样品的比磨损率降低至 39%。由于由 XPS 氧区峰值 531.85 eV 证实的氧化铁膜组成的转移膜和拉曼光谱证实了扭曲的聚合物环，摩擦系数和比磨损率降低了更大的程度。
