The tribological performance of the surfaces were qualified in linear reciprocating sliding tribological tests against balls made of di erent materials using di erent oil-based lubricants. The corresponding wear tracks were characterized by optical and scanning electron microscopy and confocal profilometry. Extending our previous work, we studied the admixture of the additive 2-ethylhexyl-zinc-dithiophosphate to a base oil containing only anti-oxidants and temperature stabilizers. The presence of this additive along with the variation of the chemical composition of the counterbodies allows us to explore the synergy of the additive with the laser-oxidized nanostructures. 2075-4442 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=152754 https://hdl.handle.net/20.500.11984/1671 Lubricant additives Laser-induced periodic surface structures (LIPSS) Wear Friction On the Role of a ZDDP in the Tribological Performance of Femtosecond Laser-Induced Periodic Surface Structures on Titanium Alloy against Different Counterbody Materials
