20.500.12556/DiRROS-18074 Influence of oil viscosity on the tribological behavior of a laser-textured Ti6Al4V alloy Laser texturing with a dimple pattern was applied to modify a Ti6Al4V alloy at the micro level, aiming to improve its friction and wear resistance in combination with oil lubrication to optimize the performance in demanding industrial environments. The tribological analysis was performed on four different dimple-textured surfaces with varying dimple size and dimple-to-dimple distance and under lubrication with three different oils, i.e., T9, VG46, and VG100, to reflect the oil viscosity’s influence on the friction/wear of the laser-textured Ti6Al4V alloy. The results show that the surfaces with the highest texture density showed the most significant COF reduction of around 10% in a low-viscosity oil (T9). However, in high-viscosity oils (VG46 and VG100), the influence of the laser texturing on the COF was less pronounced. A wear analysis revealed that the laser texturing intensified the abrasive wear, especially on surfaces with a higher texture density. For low-texturing-density surfaces, less wear was observed for low- and medium-viscosity oils (T9 and VG46). For medium-to-high-texturing densities, the high-viscosity oil (VG100) provided the best contact conditions and wear results. Overall, reduced wear, even below the non-texturing case, was observed for sample 50–200 in VG100 lubrication, indicating the combined effect of oil reservoirs and increased oil-film thickness within the dimples due to the high viscosity. oil lubrication surface modification Ti-based alloy tribology true false true MDPI Švica Angleški jezik Ni določen © 2023 by the authors Neznano 2024-02-01 14:11:01 2024-02-01 14:11:02 2024-04-18 07:32:07 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 12. 10. 2023; Št. članka: 6615; str. 1-10 iss. 19 Vol. 16 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-10-09 539.92 1996-1944 10.3390/ma16196615 168088323 RAZ_Conradi_Marjetka_2023.pdf RAZ_Conradi_Marjetka_2023.pdf 1 75AE3EF775B3DDF8A482656AF4355D48 65be4928774dc986006f07cbf6275bce1a351a988636f87fc3f50f6db0a8a31c 159bda51-c104-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24540 https://www.mdpi.com/1996-1944/16/19/6615 0 05d1eb1b-c104-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24539 Inštitut za kovinske materiale in tehnologije 0 0 0
