On the Role of a ZDDP in the Tribological Performance of Femtosecond Laser-Induced Periodic Surface Structures on Titanium Alloy against Different Counterbody Materials

Ayerdi Gómez, Jon Joseba; Llavori Osa, Iñigo; Zabala Eguren, Alaitz; Aginagalde, Andrea (MDPI, 2019)

Laser-induced periodic surface structures (LIPSS, ripples) with ~500–700 nm period were produced on titanium alloy (Ti6Al4V) surfaces upon scan processing in air by a Ti:sapphire femtosecond laser. The tribological ...

Ball-on-flat linear reciprocating tests: Critical assessment of wear volume determination methods and suggested improvements for ASTM D7755 standard

Ayerdi Cantalejo, Jon; Aginagalde, Andrea; Llavori Osa, Iñigo; Zabala Eguren, Alaitz (Elsevier B.V., 2021)

This work presents a critical assessment of wear volume determination methods for ball-on-flat linear reciprocating sliding tribological tests. It revealed that the ASTM D7755-11 standard leads to the highest relative ...
