“…Wakuda et al [33] studied the influences of the dimple size, density, and shape on the friction behavior of a contact formed by the textured ceramic disk and the non-textured steel pin under the contact pressure of 0.78GPa and the sliding speed ranging from 0.012 to 1.2 m/s. The results showed the effects of the dimple size and density on the friction reduction were similar to those under the low loading condition [23][24][25]29]. The shape of the dimple, however, was found to have negligible impact on the friction, contradicting the findings of Galda et al [25] and Yu et al [30] where the loads were much lower.…”

“…Through numerical simulations, Wang et al [28] showed the hydrodynamic pressure generation of the surface dimples was tightly related to the dimple size. Tang et al [29] demonstrated the strong influence of the adjacent dimple interactions on the hydrodynamic pressure. Yu et al [30] found the geometric shapes and orientations of dimples have an evident impact on the load-carrying capacity, while considering a single dimple instead of a dimple array on the surface.…”

This study investigates the effects of the micro-dimple texture on the friction and surface temperature performances of a ball-on-disk contact, operating under the speed and load ranges that cover typical gearing applications. Circular shaped micro-dimple arrays with different dimple center distances and dimple depths are implemented on the ball surface to quantify the impacts of these two parameters on the friction coefficient and the maximum ball surface temperature. In addition, the contacts of three surface texture combinations, namely micro-dimpled and polished ball surface versus polished disk surface, polished ball surface versus polished disk surface and ground ball surface versus ground disk surface, are compared to demonstrate any beneficial or detrimental effect of micro-dimples in heavily loaded high speed applications. This study adopts a thermal mixed EHL point contact model, whose capability and accuracy have been well demonstrated by comparing to the experimental measurements, to quantify the deterministic tribological behavior within the contact, allowing the exploration of the underlying mechanism that governs the role of micro-dimples in the elastohydrodynamic lubrication.iv

“…[7] The tribological effectiveness of singlescale surface features has been demonstrated in numerous research works including dry and lubricated conditions. [8][9][10][11] In terms of dry friction, the beneficial effects of surface structures can be mainly traced back to the storage of wear debris and a reduced contact area. [12,13] Considering lubricated conditions, the improvements can be attributed to the storage of produced wear particles, [14] a reservoir effect for lubricants, [15] and an additional hydrodynamic pressure build-up.…”

Effects of Multi‐Scale Patterning on the Run‐In Behavior of Steel–Alumina Pairings under Lubricated Conditions

In nature, many examples of multi-scale surfaces with outstanding tribological properties such as reduced friction and wear under dry friction and lubricated conditions can be found. To determine whether multi-scale surfaces positively affect the frictional and wear performance, tests are performed on a ball-on-disk tribometer under lubricated conditions using an additive-free poly-alpha-olefine oil under a contact pressure of around 1.29 GPa. For this purpose, stainless steel specimens (AISI 304) are modified by micro-coining (hemispherical structures with a structural depth of either 50 or 95 mm) and subsequently by direct laser interference patterning (cross-like pattern with 9 mm periodicity) to create a multi-scale pattern. The comparison of different sample states (polished reference, laser-patterned, micro-coined, and multi-scale) shows a clear influence of the fabrication technique. In terms of the multi-scale structures, the structural depth of the coarser micro-coining plays an important role. In case of lower coining depths (50 mm), the multi-scale specimens show an increased coefficient of friction compared to the purely micro-coined surfaces, whereas larger coining depths (95 mm) result in stable and lower friction values for the multi-scale patterns.

“…Several classes of tribological experiments were developed in order to investigate the benefits of laser surface texturing in term of reduction of friction coefficients and reduction of wear rates, mainly on steel surfaces [11][12][13][14][15]. But there is a lack of information about the interaction between laser beam and material structure and the laser beam, which plays a key role in the formation of dimples of required shapes and surface integrity [16].…”

Abstract:In this experimental investigation the laser surface texturing of tool steel of type 90MnCrV8 has been conducted. The 5-axis highly dynamic laser precision machining centre Lasertec 80 Shape equipped with the nano-second pulsed ytterbium fibre laser and CNC system Siemens 840 D was used. The planar and spherical surfaces first prepared by turning have been textured. The regular array of spherical and ellipsoidal dimples with a different dimensions and different surface density has been created. Laser surface texturing has been realized under different combinations of process parameters: pulse frequency, pulse energy and laser beam scanning speed. The morphological characterization of ablated surfaces has been performed using scanning electron microscopy (SEM) technique. The results show limited possibility of ns pulse fibre laser application to generate different surface structures for tribological modification of metallic materials. These structures were obtained by varying the processing conditions between surface ablation, to surface remelting. In all cases the areas of molten material and re-cast layers were observed on the bottom and walls of the dimples. Beside the influence of laser beam parameters on the machined surface quality during laser machining of regular hemispherical and elipsoidal dimple texture on parabolic and hemispherical surfaces has been studied.
