摘要

在本研究中，将环氧树脂和SU-8树脂及其复合材料涂覆在轴承钢上。以石墨、滑石和基础油为原料，采用旋涂法制备了复合材料。分别使用盘上球装置、光学显微镜、3D光学轮廓仪和角度仪对这两种类型的聚合物及其复合材料进行了摩擦学和表面表征测试。从结果可以看出，与SU-8聚合物（~34%）及其复合材料相比，环氧树脂及其复合材料聚合物表现出较低的摩擦系数（~0.16）、较高的耐磨性能（>102倍）、机械性能（弹性模量和硬度）的提高（~3-4倍）和更好的疏水性。此外，还建立了一个神经网络模型来确定对比磨损率和摩擦系数的影响参数。

A comparative study of tribological and mechanical properties of composite polymer coatings on bearing steel

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 (~0.16), high wear resistance properties (> 102 times), improvement in mechanical properties (elastic modulus and hardness) (~3-4 times) and better hydrophobic nature as compared to SU-8 polymer (~34%) and its composites. Furthermore, a neural network model was developed to determine the influential parameters on specific wear rate and coefficient of friction.
