“…Though some materials may adhere to the worn surface of the mating ball, dimple edge can scrape them off. 15 So, if a few bronze materials adhere to the mating ball, they can be scraped off by indented dimple edge, which can avoid the wear caused by metallic junctions of Cu/Cu. Therefore, no obvious adhesive bronze material can be observed on the worn surface of the mating ball sliding against indented dimple surface.…”

Surface texturing is an effective approach to improve the tribological properties of mechanical components. An indentation method is presented to fabricate dimple textures on bronze specimen surfaces. Graphite was selected as the mating balls in ball-on-disc wear tests. The worn surfaces and the indented dimples heaped with the thin ribbon debris were observed by microscope. The morphology and evolution of wear debris were employed to explain the influence of indented dimple textures. The experimental results indicate that the generation of thin ribbon debris is due to the edge hardening of indented dimple. The thin ribbon debris and the indented conical dimple are conducive to the debris heaping on slopes of dimples, which can facilitate the formation of the graphite-rich transfer layers on indented dimple surface. Compared with nontextured surface, indented dimple surface has lower coefficients of friction and slighter wear. The tribological properties of indented dimple surface are improved because of the edge hardening, the debris heaping and the formation of transfer layers.

“…High-energy laser irradiation can easily induce metal surface damage and metallographic changes, which subsequently affect the physical and mechanical properties of ablated materials. In addition, it is also challenging for LST to fabricate shallow textures in sub-micron range of feature size while maintaining high precision, and the cost of related equipment is relatively high [ 15 , 16 , 17 , 18 , 19 ]. Recently, ultra-precision diamond machining methods have also been proposed to fabricate high-precision surface textures [ 20 , 21 , 22 , 23 , 24 ].…”

The manufacturing of precise surface microstructures with low cost is needed for surface texturing-based surface engineering. In this paper, a device for the fabrication of surface microgroove texture on stainless steel based on ultrasonic impact peening (UIP) is proposed and investigated. First, the principle of applying the UIP into the fabrication of surface texture is analytically described. Then, the design of the UIP device, particularly the design of functional systems and mechanical structures, is carried out. Next, a UIP experimental device is built, and is further applied to fabricate microgroove textures on 316L stainless steel. The subsequent experimental characterization of microgroove morphology demonstrates the feasibility of the designed UIP device for the fabrication of stainless steel surface texture.

This study fabricated textures on the stator surface of a traveling wave ultrasonic motor (USM) using laser and investigated the tribological behavior of a polytetrafluoroethylene (PTFE) composite friction material and stator. Initially, the effect of textures with different densities was tested. As the results suggested, the generation of large transfer films of PTFE composite was prevented by laser surface texturing, and adhesive wear reduced notably despite the insignificant decrease in load capacity and efficiency. Next, the 100-h test was performed to further study the effects of texture. Worn surface and wear debris were observed to discuss wear mechanisms. After 100 h, the form of wear debris changed into particles. The wear mechanisms of friction material sliding against the textured stator were small size fatigue and slight abrasive wear. The wear height of friction material decreased from 3.8 μm to 1.1 μm. This research provides a method to reduce the wear of friction materials used in travelling wave USMs. Friction 8(2): 301-310 (2020) | https://mc03.manuscriptcentral.com/friction Jinbang LI.
