“…The lower threshold fluence for undulating grooves generation is higher than that of higher threshold fluence of LIPSS formation. The formation of periodic grooves was attributed to the spatial energy distribution by the interaction of the laser beam with the surface wave that might be induced by LIPSS [29]. Another possible mechanism for the formation of undulating grooves was attributed to the hydrodynamic processes related to wave phenomena, e.g., capillary waves [78].…”

“…The effect of polarization on undulating grooves was explored on Ti in vacuum [29]. When the laser beam polarization was rotated, the undulating grooves were also rotated, i.e., the orientation of the undulating grooves was always perpendicular to the laser beam polarization.…”

Abstract:Femtosecond laser micromachining has emerged in recent years as a new technique for micro/nano structure fabrication because of its applicability to virtually all kinds of materials in an easy one-step process that is scalable. In the past, much research on femtosecond laser micromachining was carried out to understand the complex ablation mechanism, whereas recent works are mostly concerned with the fabrication of surface structures because of their numerous possible applications. The state-of-the-art knowledge on the fabrication of these structures on metals with direct femtosecond laser micromachining is reviewed in this article. The effect of various parameters, such as fluence, number of pulses, laser beam polarization, wavelength, incident angle, scan velocity, number of scans, and environment, on the formation of different structures is discussed in detail wherever possible. Furthermore, a guideline for surface structures optimization is provided. The authors' experimental work on laser-inscribed regular pattern fabrication is presented to give a complete picture of micromachining processes. Finally, possible applications of laser-machined surface structures in different fields are briefly reviewed.

“…Oak et al 118) carried out a series of studies about the corrosion behavior and biocompatibility of the Ti 45 Zr 10 Cu 31 Pd 10 Sn 4 metallic glass, and their results demonstrated that this kind of metallic glass exhibited good corrosion resistance and excellent biocompatibility in osteoblast culture test. Nagai et al 119) investigated cellular behaviors responding to the Ti-based (Ti 40 Zr 10 Cu 36 Pd 14 ) metallic glass surface irradiated with a femtosecond laser, 120) which can form periodic nanostructures on the Tibased BMG surface. 121) The results demonstrated that the number of osterblasts attached to the modified Ti-based metallic glass surfaces after 3 h of incubation.…”

Recent Progress in Ti-Based Metallic Glasses for Application as Biomaterials

Ti-based bulk metallic glasses are of great interest in biomedical applications due to their high corrosion resistance, excellent mechanical properties and good biocompatibility. This article reviews recent progress in the development of Ti-based metallic glasses for the application as biomaterials. Ti-based (TiZrCuPd, TiZrCuPdSn, and TiZrCuPdNb) bulk metallic glasses without toxic and allergic elements have been developed. These glassy alloys exhibited high glass-forming ability, high strength, large plasticity, good corrosion resistance and excellent biocompatibility, which open possibilities to create Ti-based metallic glass implants. Using a spark plasma sintering process, large-size Ti-based bulk metallic glasses and the composites with hydroxyapatite, as well as porous glassy alloys having approximate Young's modulus with that of bone were developed.
