“…Wang et al [10] demonstrated the coefficient friction of the laser-textured surface with periodic surface structures was reduced by approximately 70-80% compared to the original Ti6Al4V alloy surface. Similar results were observed by Song et al [9]. Interestingly, Sadeghi [13] owed that the density ratio of grooves significantly affects wear behavior.…”

“…These advantages made lasertexturing an unbeatable process to other texturing methods, such as embossing, vibro-rolling, abrasive jet machining, micro-coining, roller-coining, micro-casting, reactive ion beam etching, electrical discharge machining, as showed by Reddy et al [7]. Many research showed [8][9][10][11], that lasertexturing of metal base materials can lead to a change in the interaction between surfaces in friction contact, resulting in better lubrication and enhanced wear resistance. However, the size, depth, and density of the laser-textured pattern have significant effects on the degree of wear and the coefficient of friction.…”

“…Lin et al [12] highlighted the main advantages of laser-textured surfaces as the potential for continuous lubrication owing to the presence of lubricant on the textured surface and the entrapment of wear debris, thus reducing overall wear. In literature data, to improve the tribological behaviour of biomaterials, researchers have proposed texture patterns such as micro-dimple array [13,14], micro-groove cross-hatched [9,[15][16][17], and groove system forming trust [18]. Wang et al [10] demonstrated the coefficient friction of the laser-textured surface with periodic surface structures was reduced by approximately 70-80% compared to the original Ti6Al4V alloy surface.…”

This paper analyzes the tribological behavior of the Ti6Al4V ELI alloy subjected to laser texturization for medical purposes. Laser texturing enables one to observe specific patterns of the material surface at established depths. Microtexturing of the samples was performed using a 355 nm picosecond laser. The influence of the microtexturing process (depending on the process parameters) on the geometric parameters of the proposed laser texturing pattern was evaluated. Selected samples were subjected to tribological testing using the ball-on-plate technique in dry and lubricant-sliding methods (in Ringer solution). The wear properties were evaluated by comparing the coefficient friction, wear volumes, and wear ratio. A scanning electron microscope characterized the morphologies of the wear scar and the wear mechanism. The experimental results show that the surface texturing and the changes in microgrooves can reduce wear. The results indicate, that samples after laser texturing were characterized by 15% higher microhardness, compared to those in the initial state. It was found, a 26% reduction in friction coefficient and 29% in the wear volume compared to the smooth, untextured surface samples under lubricated conditions. The decrease in value of the coefficient friction and wear volume for the samples after the laser texturing process is an effect of synergistic of entrapped wear debris in micro-grooves and increased hardness for samples after laser textured.

“…Laser texturing proves to be a precise, accurate, reproducible, and environmentally friendly technique for modifying surfaces. Literature findings reveal that the laser-texturing process not only results in an enhancement of tribological behavior attributed to improved lubrication [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], but also leads to superior microbiological properties owing to the contact guide effect [ 22 , 23 ].…”

Titanium-based materials are the most widely used materials in biomedical applications. However, according to literature findings, the degradation products of titanium have been associated with potential allergic reactions, inflammation, and bone resorption. The corrosion process of Ti-6Al-4V in the human body environment may be exacerbated by factors such as reduced pH levels and elevated concentrations of chloride compounds. Coatings made of biopolymers are gaining attention as they offer numerous advantages for enhancing implant functionality, including improved biocompatibility, bioactivity, wettability, drug release, and antibacterial activity. This study analyzes the physicochemical and electrochemical behavior of the Ti-6Al-4V ELI alloy subjected to PCL and PCL/TiO2 deposition by the electrospinning method. To characterize the polymer-based layer, tests of chemical and phase composition, as well as surface morphology investigations, were performed. Wetting angle tests were conducted as part of assessing the physicochemical properties. The samples were subjected to corrosion behavior analysis, which included open circuit potential measurements, potentiodynamic tests, and the electrochemical impedance spectroscopy method. Additionally, the quantification of released ions post the potentiodynamic test was carried out using the inductively coupled plasma atomic emission spectrometry (ICP–AES) method. Cytotoxicity tests were also performed. It was found that surface modification by depositing a polymer-based layer on the titanium substrate material using the electrospinning method provides improved corrosion behavior, and the samples exhibit non-toxic properties.
