Microlubrication effect by laser-textured steel surfaces
Peter Andersson,Jari Koskinen,Simo Varjus,Yvonne B. Gerbig,Henry Haefke,S. Georgiou,B. Zhmud,W. Buss +7 more
TL;DR: In this article, the effect of microtexturing of sliding surfaces by laser ablation and polishing was investigated, based on two independent experimental approaches with oil-lubricated smooth and laser-textured steel surfaces in oscillating sliding contact with a steel ball.
Journal ArticleDOI
Laser microstructuring of steel surfaces for tribological applications
TL;DR: In this article, the laser-generated patterns consisting of precisely ablated microcraters were produced using a flash lamp pumped, Q-switched Nd:YAG laser.
Journal ArticleDOI
Laser treatment of tribological DLC films
G. Dumitru,Valerio Romano,H.P. Weber,Sergej M. Pimenov,Taras V. Kononenko,Jörg Hermann,S. Bruneau,Yvonne B. Gerbig,M.L. Shupegin +8 more
TL;DR: In this article, the possibilities to generate patterned diamond-like carbon (DLC) coated low wear tribological surfaces by means of laser processing were investigated, and the results showed that the friction coefficient did not increase, as compared with the unstructured and DLC coated surfaces.
Journal ArticleDOI
Comparison of nanoscale measurements of strain and stress using electron back scattered diffraction and confocal Raman microscopy
TL;DR: In this paper, electron backscattered diffraction (EBSD) and confocal Raman microscopy (CRM) with spatial resolutions of 10 nm and 100 nm, respectively, were collected across wedge indentations in (001) Si.
Journal ArticleDOI
Laser processing of hardmetals: Physical basics and applications
TL;DR: In this article, the basic physics of the laser-matter interactions and the influence of different laser parameters are discussed, with emphasis on sintered WC-Co specific features, and the collateral affected zones and their occurrence mechanisms for laser machining with both nanosecond and femtosecond pulses are discussed.
