“…The fluctuation of the friction coefficient is mainly attributed to the insufficient protection of the lubricant film, which intensifies wear as well as the generation and overflow behavior of wear debris. Additionally, the fluctuation of surface roughness has a significant impact, resulting in a relatively large fluctuation in the contact state of the friction [24]. In addition, it can be seen that the fluctuation of the friction coefficient at D = 150 µm and 250 µm is larger than that at D = 50 µm.…”

This paper investigates the effect of ultrasonic surface rolling (USR) on the fretting wear properties of the 7075 aluminum alloy. A white light interferometer, Vickers hardness tester, and X-ray diffractometer were employed to comparatively analyze the variations in surface roughness, hardness. and grain size before and after the USR treatment. The fretting tests were carried out under oil lubricated and dry fretting conditions, using a ball-on-flat contact tangential fretting tester. The worn surface morphology, wear debris, and chemical composition were analyzed using an optical microscope (OM), a scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS), etc. The results revealed that after USR treatment, the surface roughness was reduced by 90%, the hardness was increased by 13HV, and the grains were refined. Moreover, the wear was reduced under oil lubrication conditions but increased under dry fretting conditions. It can be concluded that the microstructure and mechanical properties of the 7075 aluminum alloy surface can be enhanced by the USR treatment. The improved fretting performance in oil should be attributed to the increased surface hardness, which helps reduce abrasive wear and plastic deformation. However, under dry fretting conditions, the wear was increased due to the presence of hard debris particles that peel off from the USR-treated surface, leading to aggravated abrasion.

“…20CrMnTi is an ideal material for picking spindle because of its economy, good processability and anti-fatigue properties [2,3]. However, as a low carbon steel, the hardness and wear resistance of 20CrMnTi is poor [4]. When used as wearresistant materials, surface strengthening treatments such as carburizing and chromium plating are necessary [1,5].…”

A novel CrCx/C-Cr multilayer coating for cotton picking spindle was prepared on 20CrMnTi substrate by PVD technology. Compared with the traditional electroplated chromium coating, the CrCx/C-Cr coating has dense structure, and no micro-cracks were observed on the surface. The results of nanoindentation show that the nano-hardness of CrCx/C-Cr coating is about 8.46 GPa and 78.5% higher than that of the substrate. Compared with electroplated chromium coating, PVD coating has lower friction coefficient and wear rate, which indicates a better wear resistance property. The multilayer PVD coating provided is expected to replace the high-pollution chromium coating for cotton picking spindle.

“…Besides the corrosion performance of the substrate, surface coating and surface modification technologies are also frequently adopted to improve the corrosion resistance of components. Surface modification technologies such as ultrasonic surface rolling [32], shot peening [33], nitriding and carburizing [34,35] are applied to improve the wear resistance performance. Tan et al [36] adopted laser shock peening (LSP) to improve the surface wear resistance of AlSi7Mg0.6 aluminum alloy under impact-sliding wear.…”

The wear performance of AlSi7Mg0.6 aluminum alloy, a casting aluminum alloy used in positioning devices for catenary systems of high-speed railways which fail frequently on lines where the speed of trains is higher than 300 m/s, is discussed in this study. It was estimated that sliding contact wear occurred and mainly contributed to the failure. To explore the competing mechanism for frictional wear failure, frictional experiments based on three groups of sliding distance (0.5 mm, 1.5 mm and 3.0 mm) and four groups of applied loads (20 N, 50 N, 100 N and 200 N) were implemented. Three-dimensional morphological observation results revealed that the wear volumes at a sliding distance of 0.5 mm were only about 1/10 of that at a sliding distance of 3.0 mm. It was also revealed that the wear volume based on a sliding distance of 3.0 mm and applied load of 20 N was still much larger than the wear volume under a sliding distance of 0.5 mm and applied load of 200 N. SEM observation of the microstructures revealed that abrasive wear was the dominant wear mechanism in dry sliding friction conditions. A simplified positioning device model was also established to study the influence of tension force on wear performance. The simulation results revealed that smaller tension force between the positioning support and positioning hook would lead to higher relative sliding distance and larger wear depth. Sliding contact friction should be avoided due to relatively large wear efficiency compared with rolling contact friction. Both experimental and simulation results suggested that proper tension force was preferred in assembling components which could ensure rolling contact friction rather than sliding contact friction.
