Laser Surface Modification of Ti6Al4V Implants
To improve the biocompatibility of implants, surface medication is a common practice. Depending on the surface medication process, the physical and/or chemical properties of the surface are altered, keeping the bulk properties same. The flexibility and wide application potential of laser as a surface modification tool gives it certain advantages over the traditional physical and chemical proces...
متن کاملSurface Modification of Polymer Materials Induced by Laser Irradiation
We report on the surface modification effects using allyl‐diglycol CR39 polymer induced by laser irradiation at 157 nm F2 laser (VUV) and 248 nm KrF laser. The motivation is to investigate the ablation effects on this polymer in optical waveguides application the ablation effects on this polymer in optical waveguides. Fabrication of waveguides has been observed using continuous wave (CW) at 244...
متن کاملSurface Modification by EUV laser Beam based on Capillary Discharge
Many applications require surface modification and micro-structuring of polymers. For these purposes is mainly used ultraviolet (UV) radiation from excimer lamps or excimer lasers. However, these sources have a decided disadvantage degrading the polymer deep inside due to relatively big radiation penetration depth which may exceed 100 μm. In contrast, extreme ultraviolet (EUV) radiation is abso...
متن کاملSurface Modification of TIMETAL 834 by Excimer Pulse Laser
Ti alloys become very popular in various engineering fields due to its light weight, high strength and good corrosion resistance properties. Nevertheless, its application is limited in many areas like: tribology, high temperature oxidation and aggressive corrosion fields due to its poor surface properties. Therefore, the proper surface treatment is required to increase the usageof Ti alloys in ...
متن کاملLaser surface modification of hydroxyapatite and glass-reinforced hydroxyapatite.
Surface treatment of materials with excimer laser radiation often results in the formation of a rough columnar or cone-shaped surface topography, which leads to a considerable increase in the surface area. As a result, the search for a non-porous bioactive material with adequate mechanical properties and a high surface to volume ratio, similar to porous materials, which could be used for drug d...
