Laser surface structuring of AZ31 Mg alloy for controlled wettability.
Structured surfaces exhibit functional properties that can enhance the performance of a bioimplant in terms of biocompatibility, adhesion, or corrosion behavior. In order to tailor the surface property, chemical and physical methods can be used in a sequence of many steps. On the other hand, laser surface processing can provide a single step solution to achieve the designated surface function w...
متن کاملNanosecond Laser Surface Patterning of Bio Grade 316L Stainless Steel for Controlling its Wettability Characteristics
In this work, potential of the nanosecond laser processing technique on manipulating the surface wettability of 316L bio grade stainless steel is investigated. Results show that the steel wettability toward water, improves significantly after the laser treatment. Different analyses are assessed in correlation with wettability using Scanning Electron Microscope (SEM), Scanning Tunneling Microsco...
متن کاملMechanism of surface modification of CeO in laser remelted alloy
The microstructures and properties of laser remelted alloy spray coatings were studied by means of wear testing, corrosion testing, microhardness testing, scanning electron microscopy, electron probe microanalysis and transmission electron microscopy. The results show that the wear and corrosion resistance of laser remelted alloy spray coatings is remarkably increased by the addition of CeO . T...
متن کاملModification of Anodized Mg Alloy Surface By Pulse Condition for Biodegradable Material
Magnesium is used implant material potentially for non-toxicity to the human body. Due to the excellent bio-compatibility, Mg alloys is applied to implants avoiding removal second surgery. However, it is found commercial magnesium alloys including aluminum has low corrosion resistance, resulting subcutaneous gas bubbles and consequently the approach as permanent bio-materials. Generally, Alumin...
متن کاملSurface Wettability Modification of Cyclic Olefin Polymer by Direct Femtosecond Laser Irradiation
The effect of laser irradiation on surface wettability of cyclic olefin polymer (COP) was investigated. Under different laser parameters, a superhydrophilic or a superhydrophobic COP surface with a water contact angle (WCA) of almost 0° or 163°, respectively, could be achieved by direct femtosecond laser irradiation. The laser power deposition rate (PDR) was found to be a key factor on the wett...
