An ultrasonic nanocrystalline surface modification (UNSM) process followed by laser surface texturing (LST) was applied to graphite cast iron to improve the friction and wear behavior. The surface hardness of the UNSM-treated and UNSM + LST-treated specimens was increased significantly compared to the polished and the LST-treated specimens. The friction and wear behavior of the specimens was assessed using a ball-on-disk friction tester at an applied load of 10 N and a speed of 5cm/s in both dry and lubrication conditions. The friction coefficient of the UNSM-, LST-and the UNSM+LST-treated specimens reduced in both dry and lubrication conditions compared to the polished specimen by 64, 30, and 64%, and 63, 67, and 75%, respectively. In lubrication condition, the friction coefficient of the UNSM-and LST-treated specimens was further reduced by about 30 and 25% by UNSM+LST processes. In dry Downloaded by [University of Kentucky Libraries] at 00:44 25 June 2016 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2condition, the UNSM+LST-treated specimen exhibited a reduction in the friction coefficient of 46% compared to the LST-treated specimen, whereas no reduction in friction coefficient was found compared to the UNSM-treated specimen. The wear resistance of the UNSM-, LST-and the UNSM + LST-treated specimens was enhanced by 22%, 11%, and 37% in the dry condition, respectively whereas a minuscule wear was observed in lubrication condition that was difficult to quantify in our experiment. The synergy effect of UNSM and LST processes was effectively combined to improve the friction and wear behavior of graphite cast iron.

“…Yin et al (2019) established a lubrication model considering surface roughness for textured cylinder liners and found that by fabricating surface texture the lubrication performance of cylinder liners was increased and wear was reduced. Tripathi et al (2016) performed a ball-on-disk tribological test to evaluate the tribological performance of the specimens. A certain operation condition was selected and laser surface texturing (LST) was used to fabricate surface texture.…”

Purpose The purpose of this study is to investigate the influence of dimple radius, depth and density on the lubrication performance of the plunger. Design/methodology/approach A lubrication model was adopted to consider eccentricity and deformation during the working process of the plunger, and a rig test was performed to confirm the simulation results. The texture was fabricated using laser surface texturing. Findings The simulation results suggested that when dimple radius or depth increases, oil film thickness of the plunger increases before decreasing, and asperity friction displays an opposite trend. Therefore, appropriate microdimple texture could facilitate lubrication performance improvement and reduce the wear. Microdimples were then lased on the plunger surface, and a basic tribological test was conducted to validate the simulation results. The experimental results suggested that the average friction coefficient decreased from 0.18 to 0.13, a reduction of 27.8%. Social implications The introduction of microdimple on a plunger couple to reduce friction and improve lubrication is expected to provide a new approach to developing high-performance plunger couple and improve the performance of the internal combustion engine. If applied, the surface texture could help reduce friction by around 27% and cap the cost relative to the plugger friction. Originality/value The microdimple texture was introduced into the plunger couple of a vehicle to reduce the friction and improve the performance. Findings suggested that surface texture could be used in the automotive industry to improve oil efficiency and lubrication performance.

“…Most of the studies reveal that, these microtextures act like micropockets for wear debris in either dry or lubricated sliding conditions. These microstructures also act as microreservoirs for lubricant under the conditions of lubrication starvation and are predictable to form a lubricating film which leads to reduced friction 21–23 …”

Tribological properties of Ti3SiC2 ceramic and Ti3SiC2/GNP composite were investigated using fretting sliding against Si3N4 ball counter body at a load of 50 N for a sliding distance of 900 m, under non‐textured lubricated (NTL), textured lubricated (TL) condition, and textured lubricated high temperature (TLHT). This paper presents the influence of laser surface texturing (LST) on Ti3SiC2 and its graphene nanoplatelets (GNP) reinforced composite established through spark plasma sintering (SPS), tested under fretting wear conditions. The coefficient of friction and wear rate of Ti3SiC2 and its graphene nanoplatelets reinforced composites were incontrovertibly enhanced with laser surface texturing as compared to non‐textured Ti3SiC2 and its GNP composite. The TL surface of Ti3SiC2 composite reinforced with 15% GNP showed the lowest COF and wear rate. Almost negligible changes were observed for TLHT tests. The LST proved to an efficient technique for enhancing the friction and wear properties of Ti3SiC2 and Ti3SiC2/GNP composite.
