“…noted strong influence of surface roughness on sliding conditions [2]. However, relation between surface morphology and friction behaviour has been mainly studied in the mono-directional sliding [3] or in the FS conditions in order to evaluate the influence of roughness on wear behaviour [4]. In this paper, focus will be given on small amplitude, fretting sliding conditions.…”

Abstract:In many industrial applications where fretting damage is observed in the contact (e.g. rotor/blade, electrical contacts, assembly joint, axe/wheel, clutch) the external loadings or geometry design cannot be changed.Therefore, the surface preparation and finishing process become essential to control and reduce the damage caused by fretting. In this paper, the authors present the experimental study of the initial surface roughness and machining process influence on fretting conditions in both partial and full sliding regimes. Surfaces prepared by milling and smooth abrasive polishing processes have been analysed. The influence of roughness on sliding behaviour and analysis of friction have been reported. Also, the contact pressure influence and qualitative analysis of fretting wear scar have been presented.

“…In this sample, the porosity is low and the pore size is small, making the surface smoother [27]. And combined with the higher mechanical properties of S1 due to the strong intergranular bonding and low porosity, the coefficient of friction and wear rate are reduced [28]. At the same time, the sample with fine-grained zirconia structure also has good wear resistance under high-speed sliding [24].…”

“…In addition, according to the XRD and EPMA analysis, the sample also contains unreacted alumina particles, and the strengthening and toughening effect of the presence of alumina particles and columnar mullite significantly improves the mechanical properties of the material [25,26]. Good comprehensive mechanical properties combined with extremely low porosity make it difficult for materials to undergo large brittle fracture and shedding during friction, thus improving the wear resistance of the material [23,27,28].…”

“…6 In the case of insufficient lubrication, it acts like a micro oil reser-voir7, also, textures can capture debris to prevent the contact surface from severe wearing. 8,9 When the relative speed of the tribo-pairs is high, fluid pressure drops due to flow expansion inner the dimple which further leads to the reductions of the shear stresses. 10 So far, there has been a lot of research work devoted to the influence of surface texture on the contact surface of the tribo-pair.…”

Surface texturing, a well-known method to increase tribo-pair tribological performance, is widely used and of great importance in industrial manufacturing. By designing reasonable surface texture on two contact surfaces, the load-carrying capacity, wear resistance, and coefficient of friction of the tribo-pairs can be significantly improved. To investigate the influence of the macro-texture, millimeter magnitude, on the tribology performance, a large number of simulation cases were carried out in this work. And the influence of texture parameters including the ellipse aspect ratio, the depth-to-diameter ratio, density, and distribution on tribology performance was studied using the hydrodynamic lubrication model which was verified through a sample experiment of piston ring and cylinder liner tribo-pairs. In addition, a Taguchi algorithm was used to find the most suitable texture parameters. The results show that the influence of density on the coefficient of friction and load-carrying capacity is of significance and 20% density is sufficient for tribology performance. Dimple size and distribution had a more significant influence on tribology performance.
