| 摘 要： |
In this study, epoxy and SU-8 resin along with its composites was coated over bearing steel. The graphite, talc and base oil were used to fabricate the composites using spin-coater. The tribological and surface characterisation tests were performed on both type of polymer and its composite using ball-on-disk setup, optical microscope, 3D optical profilometer, and goniometer, respectively. From the results, it can be seen that epoxy and its composites polymer showed lower coefficient of friction (similar to 0.16), high wear resistance properties (> 10(2) times), improvement in mechanical properties (elastic modulus and hardness) (similar to 3-4 times) and better hydrophobic nature as compared to SU-8 polymer (similar to 34%) and its composites. Furthermore, a neural network model was developed to determine the influential parameters on specific wear rate and coefficient of friction.
在本研究中，环氧树脂和SU-8树脂及其复合材料被涂覆于轴承钢表面。石墨、滑石粉和基础油通过转印涂布法制备了复合材料。采用球-盘装置、光学显微镜、三维光学轮廓仪和万能角度计分别对两种聚合物及其复合材料进行了摩擦学和表面特性测试。结果表明，环氧树脂及其复合材料表现出较低的摩擦系数（约为0.16）以及优异的耐磨性能（>与SU-8聚合物及其复合材料相比，其机械性能（弹性模量和硬度）得到显著改善（约提升3至4倍），且疏水性更优（约提升34%）。此外，还开发了神经网络模型，用于确定影响特定磨损率和摩擦系数的关键参数。 |
