Experimental analysis of the effects of laser surface texturing on tribological properties of PTFE/Kevlar fabric composite weave structures

Synergetic effects of surface texturing and solid lubricants to tailor friction and wear – A review

“…In addition to the observed effect on wear, textures rubbing against PTFE counter-bodies may also lower the COF (reduction on the order of 10%) [183,184] and improve the energy efficiency in ultrasonic motors (improvement by about 30%) [185,186]. These improvements were explained by the storage of lubricious wear debris in textures, thus reducing abrasion and adhesion due to the discontinuous contact area.…”

“…Most of these employed hard textured substrates such as stainless steel [179][180][181][182][183], bronze [184][185][186], silicon [187] or laminated ceramics [188,189], which were rubbing against an untextured PTFE nano-composite. Surface textures were mainly produced by LST using lasers with pulse durations ranging from micro- [179,181,[184][185][186] and nano- [188,189] to pico- [182] and femtoseconds [180,187].…”

Influence of sliding orientation on tribological properties of hybrid PTFE/Kevlar fabric composites

“…By lling with PTFE and graphite as lubricants in LST microconcavities, the tribological performance of the friction pair was enhanced signicantly. 10,11 Additionally, the textile structures, weave density, we density, and yarn twist of fabric liners are important factors affecting the tribological performance of fabric liners and have also been extensively studied. [12][13][14] Results indicated a fabric liner with a satin 8/5 structure demonstrated the best antifriction and wear resistance due to the large PTFE proportions on the friction surface.…”

Effects of laser processing conditions on wettability and proliferation of Saos-2 cells on CoCrMo alloy surfaces

“…LST was successfully employed by the automotive industry to treat cylinder liners of internal combustion engines and thus to improve fuel consumption and reduce engine wear [12]. It was also employed as a mean of reducing friction and wear between other types sliding surfaces such as PTFE/Kevlar fabric composites [13], polymers [14], and more [15]. More recently LST found applications in medical industry, specifically to modify surfaces of orthopedic implants.…”
