Ceria nanofillers were incorporated into PEEK coatings at concentrations of 0.5, 1.5, and 3 wt% and applied to mild steel samples using an electrostatic spraying technique. The tribological performance of these coatings was assessed under various loads and sliding speeds. XRD, FTIR, and microhardness tests were conducted to characterize the chemical and mechanical properties of the coatings. The 1.5 wt% ceria-reinforced PEEK coating outperformed the pristine PEEK and other concentrations in terms of wear resistance. The counterface material did not affect the wear resistance of the optimized PEEK/1.5 wt% ceria nanocomposite coating, which also demonstrated superior wear resistance after UV exposure as compared to that of pristine PEEK coatings.
将氧化铈纳米填料以0.5、1.5和3 wt%的浓度掺入聚醚醚酮（PEEK）涂层中，并使用静电喷涂技术将其应用于低碳钢样品。在各种载荷和滑动速度下评估这些涂层的摩擦学性能。进行X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）和显微硬度测试以表征涂层的化学和机械性能。在耐磨性方面，1.5 wt%氧化铈增强的PEEK涂层优于原始PEEK和其他浓度的涂层。对偶面材料不影响优化后的PEEK/1.5 wt%氧化铈纳米复合涂层的耐磨性，与原始PEEK涂层相比，该涂层在紫外线照射后也表现出优异的耐磨性。
