This paper reports research on the frictional behavior of a textured surface against several materials under dry and lubricated conditions, and this is aimed to provide design guidelines on the surface texturing for wide-ranging industrial applications. Experiments were performed on a tribo-tester with the facility of simulating A ball-on-plate model in reciprocating motion under dry, oil-lubricated, and water-lubricated conditions. To study the frictional behavior of textured SiC against various materials, three types of ball-bearing -elements, 52100 steel, silicon nitride (SiN), and polytetrafluoroethylene (PTFE), were used. Friction and wear performance of an un-textured surface and two types of widely used micro-scale texture surfaces, grooves and circular dimples, were examined and compared. The results demonstrated that the effect of surface textures on friction and wear performance is influenced by texture parameters and the materials of friction pairs. The circular-dimple texture and the groove texture, with certain texture parameters, played a positive role in improving friction and wear performance under specific operating conditions used in this research for SiC-steel and SiC-SiN friction pairs; however, there was no friction and wear improvement for the textured SiC-PTFE friction pair. The results of this study offer an understanding and a knowledge base to enhance the performance of bearing elements in complex interacting systems.
本文报道了关于在干燥和润滑条件下纹理表面与几种材料之间摩擦行为的研究,旨在为广泛的工业应用提供表面纹理化的设计指南。在一台具有模拟能力的摩擦磨损试验机上进行了实验,该试验机可在干燥、油润滑和水润滑条件下模拟往复运动的球-盘模型。为了研究纹理化碳化硅与各种材料之间的摩擦行为,使用了三种类型的滚珠轴承元件:52100钢、氮化硅(SiN)和聚四氟乙烯(PTFE)。研究并比较了无纹理表面以及两种广泛使用的微尺度纹理表面(凹槽和圆形凹坑)的摩擦和磨损性能。结果表明,表面纹理对摩擦和磨损性能的影响受纹理参数和摩擦副材料的影响。对于碳化硅-钢和碳化硅-氮化硅摩擦副,在本研究使用的特定操作条件下,具有特定纹理参数的圆形凹坑纹理和凹槽纹理在改善摩擦和磨损性能方面发挥了积极作用;然而,纹理化的碳化硅-聚四氟乙烯摩擦副的摩擦和磨损性能并未得到改善。本研究结果为提高复杂相互作用系统中轴承元件的性能提供了理解和知识库。
