研究了30vol %碳纤维增强聚醚醚酮（CFRPEEK）在不同水润滑温度下对AISI 431钢的摩擦学性能。在圆盘对圆盘接触试验装置上进行了不同工况下的摩擦磨损试验。结果表明，润滑剂温度对CFRPEEK与AISI 431钢的摩擦磨损性能有显著影响。CFRPEEK的平均摩擦系数和磨损率随润滑剂温度的升高而升高。然而，在不同的水润滑温度下，AISI 431钢的磨损率与CFRPEEK的磨损率没有正相关关系。利用环境扫描电镜和光学显微镜对CFRPEEK和AISI 431钢的原始表面和磨损表面进行了成像。CFRPEEK与AISI 431钢摩擦的主要摩擦学机制为黏着磨损，提高润滑剂温度可加速磨损。
ABSTRACT The tribological behavior of 30 vol% carbon fiber–reinforced polyetheretherketone (CFRPEEK) against AISI 431 steel under different temperatures of water lubrication was investigated. Friction and wear tests were carried out on a disc-on-disc contact test apparatus under different operating conditions. The results reveal that the lubricant temperature has a significant effect on the friction and wear properties of CFRPEEK sliding against AISI 431 steel. The average friction coefficient and wear rate of CFRPEEK increase with increasing lubricant temperature. However, the wear rate of AISI 431 steel did not have a positive correlation with the wear rate of CFRPEEK under different temperatures of water lubrication. Moreover, the original and worn surfaces of CFRPEEK and AISI 431 steel were imaged by environmental scanning electron microscopy and optical microscopy, respectively. The main tribological mechanisms of CFRPEEK sliding against AISI 431 steel were adhesive wear, and increasing the temperature of the lubricant could accelerate wear.
