“…Four tribological tests were conducted for each material on a purpose-built coaxial tribometer shown in Fig. 1, the configuration of this device was described in earlier work [26,29]. The test consists in putting a cylindrical pin made of AISI9840 steel into contact with a specimen of the ductile material under a normal load of 100 N. The pin rotates around its own axis for 300 s at constant angular speed of 60 rpm.…”

Tribological and Microstructural Characterization of Ultrafine Layers Induced by Wear in Ductile Alloys

This work studies the ultrafine subsurface layer produced in Al-Sn and Cu alloys in contact with AISI9840 steel. The tribological tests were conducted at room temperature without lubrication in a coaxial tribometer. A first microstructural characterization was performed using conventional scanning electron microscopy (SEM) and atomic force microscopy (AFM). Grain refinement mapping was performed by means of Electron Backscattering Diffraction (EBSD). The wear process, during which tribolayers are formed, leads to significant differences between the structure of the sub-micrometrical layer below the tribolayer and that of the bulk. SEM images show severe mechanical mixing in the surface of the worn zones, whereas EBSD observations allow identifying the mechanically homogenized layers as a sub-micro-crystalline material with a cellular structure aligned along the sliding direction.

“…Interestingly, they leave sharp projections in the contact plane of the machined surface [1]. It is observed that a burnished surface is smoother than an abrasively The changes in the surface characteristics due to burnishing will cause improvements in surface hardness, surface roughness, wear resistance, fatigue and corrosion resistance as claimed by many authors [1 & 3-5] which in turn improve corrosion resistance, wear resistance [4,[12][13], tensile strength [1], larger maximum residual stress in compression [9][10][11] and better roundness [12].…”

“…Proofs have shown that SPD induced nano-sized/ultrafine grained materials possess appealing surface integrity properties compared with their coarse-grained counterparts [13][14][15]. Burnishing is also an SPD process with high strain and strain-rate [15].…”

“…Wang et al prepared a nanocrystalline layer of about 10 µm thick on the surface of a low carbon steel plate by means of surface mechanical attrition treatment. Experiment results showed that the friction coefficient (FC) decreases and the wear resistance increases with the existence of nanocrystalline layer [10]. Lu et al produced a gradient nanograined surface layer by a newly developed surface mechanical grinding treatment.…”

Abstract:The dry sliding friction and wear behaviors of TC11 titanium alloy subjected to the ultrasonic impacting and rolling process (UIRP) were studied in the present work. The microstructure of the deformation layer and the morphology of the worn surfaces were observed. The results clearly show that the wear performance of TC11 alloy after UIRP is better than that of TC11 alloy before UIRP under the same testing conditions. This can be attributed to the gradient nanostructure, work hardening, and low surface roughness of the treated surface layer. For the untreated samples, wear resistance first decreases and then increases with the increase of the sliding speed. Both the friction coefficient (FC) and wear rate reach a maximum value at a sliding speed of 478 r/min, and the corresponding worn surface is the most serious. While for UIRP treated samples, better friction and wear behaviors are obtained at a sliding speed of 478 r/min. This is because the deformation layer plays a protective role against wear.
