Journal ArticleDOI
Femtosecond laser-induced periodic surface structures on steel and titanium alloy for tribological applications
Jörn Bonse,R. Koter,M. Hartelt,D. Spaltmann,Simone Pentzien,S. Höhm,Arkadi Rosenfeld,Jörg Krüger +7 more
TL;DR: In this paper, laser-induced periodic surface structures (LIPSS, ripples) were generated on stainless steel (100Cr6) and titanium alloy (Ti6Al4V) surfaces upon irradiation with multiple femtosecond laser pulses (pulse duration 30 fs, central wavelength 790 nm).
Journal ArticleDOI
Tribological performance of femtosecond laser-induced periodic surface structures on titanium and a high toughness bearing steel
Jörn Bonse,R. Koter,M. Hartelt,D. Spaltmann,Simone Pentzien,S. Höhm,Arkadi Rosenfeld,Jörg Krüger +7 more
TL;DR: In this paper, laser-induced periodic surface structures (LIPSS, ripples) were processed on steel (X30CrMoN15-1) and titanium (Ti) surfaces by irradiation in air with linear polarized femtosecond laser pulses with a pulse duration of 30 f at 790 nm wavelength.
Journal ArticleDOI
Femtosecond Laser Texturing of Surfaces for Tribological Applications.
TL;DR: The paper reviews the current state-of-the-art in fs-LST, with a focus on the tribological performance (friction and wear) of specific self-organized surface structures (so-called ripples, grooves, and spikes) on steel and titanium alloys.
Journal ArticleDOI
The influence of surface roughness on the adhesion force
TL;DR: In this article, an atomic force microscope between polymer balls attached to a cantilever and a silicon wafer under ultra high vacuum conditions was used to measure the adhesion force.
Proceedings ArticleDOI
Applications of laser-induced periodic surface structures (LIPSS)
Jörn Bonse,Sabrina V. Kirner,S. Höhm,Nadja Epperlein,D. Spaltmann,Arkadi Rosenfeld,Jörg Krüger +6 more
TL;DR: In this article, the authors reviewed current applications of laser-induced periodic surface structures (LIPSS), including the colorization of technical surfaces, the control of surface wetting, the tailoring of surface colonization by bacterial biofilms, and the improvement of the tribological performance of nanostructured metal surfaces.
