Abstract
In order to meet the challenges for friction and wear of mechanical moving components under harsh lubrication circumstances, the development of polymer-based and self-lubricating composites had received great attention. The tribological performance of several nanoparticles with similar hardness effects (Si3N4, ZrO2, SiC and Al2O3) filled with EP was investigated. The mechanical strength and tribological properties of the prepared composites are greatly improved. More encouragingly, our work had been demonstrated that Al2O3 nanoparticles afforded extraordinarily low friction and wear. A robustness tribofilms consisting of C-materials, nanocrystalline iron oxide and abundant Al2O3 nanoparticles products improved the boundary lubrication capability, suggesting that the tribological behaviors of contrastive various nanoparticles was closely dependency on the tribofilm. This work opens up opportunities formulating high-performance polymer composites for a wide range of applications subjected to harsh lubrication conditions.
