| 摘 要： | 为研究AlCoCrFeNiCu高熵合金在强氧化的过氧化氢介质中的摩擦学性能,采用销盘磨损试验机测试了AlCoCrFeNiCu合金与3种工程陶瓷组成摩擦副在90％过氧化氢介质中的摩擦学性能,采用SEM、EDS、白光共焦显微镜等分析了磨损表面,并且探讨了高熵合金与3种陶瓷配副在高浓度过氧化氢中的磨损机理.结果表明:在高浓度过氧化氢中,AlCoCrFeNiCu合金与碳化硅和氮化硅陶瓷配副具有较低的摩擦系数和较小的磨损;AlCoCrFeNiCu/ZrO2摩擦副的主要磨损机制为黏着磨损和磨粒磨损,同时伴随有氧化磨损;AlCoCrFeNiCu/SiC摩擦副和AlCoCrFeNiCu/Si3N4摩擦副的主要磨损机制为抛光型氧化磨损并伴随有轻微的三体磨粒磨损;AlCoCrFeNiCu/Si3N4摩擦副还伴随有边界润滑效应.

| Abstract: | To investigate the tribological properties of AlCoCrFeNiCu high-entropy alloy in hydrogen peroxide with strong oxidizability, a series of pin-on-disk tribo-tests were carried out using AlCoCrFeNiCu as pin and three types of engineering ceramics (ZrO2, SiC and Si3N4) as disk in a 90% hydrogen peroxide. The characterization techniques, including white light confocal microscope (CM), scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS), were employed to analyze the worn surfaces, and the wear mechanism of AlCoCrFeNiCu/ceramic tribo-pairs was discussed. The results showed that when sliding against SiC and Si3N4 ceramics, the AlCoCrFeNiCu pins had mild wear and low friction coefficient. The wear mechanism of AlCoCrFeNiCu/ZrO2 tribo-pair was a combination of adhesive wear, abrasive wear and oxidative wear. Both AlCoCrFeNiCu/SiC and AlCoCrFeNiCu/Si3N4 tribo-pair exhibited polishing oxide wear and three-body abrasive wear. The effect of boundary lubrication was found for AlCoCrFeNiCu/Si3N4 tribo-pair. |
