“…The microscopic observation of the laser surface texturing of the samples after modification by the PVD method showed a coarse ablated surface, where the edge of the groove appears to be continuous; only a few corrugated grooves with chunks of residues scattered inside the groove and the heat-affected zone on the treated surfaces have also been observed. In the position close to the edge of the hexagon there is a little accumulation of the molten matters, which leads to a convex structure [27,58,59].…”

“…The texturing process parameters were presented in Table 3. The path of laser texturing was the tightly arranged regular hexagonal honeycomb pattern with the side length of 0.29 mm (Figure 2) [27,44,45]. Before testing, all samples were placed in an ultrasonic bath for 15 min.…”

“…Among the many different types of coatings currently used for biomedical purposes, very common and relatively easy to perform are TiN and CrN coatings, which are designed to increase not only the corrosion resistance of pure titanium but also to changing the wetting angle [19,20]. Surface chemistry (i.e., wetting angle) together with its surface morphology are critical factors that could affect osseointegration [21,22], so to increase the possibility of bone tissue growth, additional methods of treatments are considered, such as laser texturing [23][24][25][26][27]. Some work also suggests that surface texturing could be a method to enhance tribological properties [27].…”

The human body is an extremely aggressive environment in terms of corrosion. Titanium and its alloys are one of the most popular biomaterials used for implant applications due to biocompatibility. However, every element introduced into the body is treated as a foreign body. The human body’s immune response may, therefore, lead to implant rejection and the need for reoperation. For this purpose, it seems important to carry out surface modifications by applying coatings and inter alia by texturing to implants. The objective of this paper is to investigate the effect of surface treatment on the chosen properties of the pure titanium (Grade II) samples obtained by selective laser melting (SLM) processing. The samples were divided into five groups: Initial state (after polishing), after surface modification by the physical vapour deposition (PVD) method—CrN and TiN coatings were deposited on the surface of the tested material, and after laser texturing. The paper presents the results of the microscopic investigation, chemical and phase compositions, and physicochemical and electrochemical properties of the tested samples. Based on the results obtained it can be concluded that the hybrid surface modification shows significant effects on the properties of the pure titanium. The samples with the textured PVD-deposited TiN coatings were characterized by favorable physicochemical properties and were the highest performing in terms of pitting corrosion resistance.

“…There are also some works that relate to the influence of LST parameters on the color of textured surfaces. These mainly evaluate the optical properties (n, k) of oxide films using spectrophotometry and ellipsometry techniques [24][25][26][27][28][29]. These measurements are useful for calculating spectral reflectance and can then be compared with the data measured by a spectroscope.…”

Nanosecond Pulsed Laser Irradiation of Titanium Alloy Substrate: Effects of Periodic Patterned Topography on the Optical Properties of Colorizing Surfaces

Most of the current works based on surface treatments of metals by laser marking technology are focused on the modification of the color tonality of flat surfaces, or the development of specific topography features, but the combination of both processes is not usually evaluated, mainly due to the complexity of controlling the optical properties on rough surfaces. This research presents an analysis of the influence of the micro-geometrical characteristics of periodic patterned laser tracks on the chromaticity and reflectance of Ti6Al4V substrates. The samples were irradiated with an infrared nanosecond pulsed laser in air atmosphere, taking as the control parameter the scan speed of the beam. A roughness evaluation, microscopic inspection, and absorption and chromaticity examination were conducted. Although micro-crack growth was detected in an isolated case (10 mm/s), the possibility of adjusting the result color was demonstrated by controlling the heat-affected zone thickness of the textures. The results of rough/colored combined textures allow new perspectives in industrial design to open, particularly in aesthetic applications with special properties.

Herein, the influence of laser‐ablated cracks in microdimples on the corrosion properties of Ni60/tungsten carbide (WC) coating is investigated. It is based on the dimension parameters of circular microdimples, which is optimized by unit and full‐size friction‐wear experiments for a textured plunger and sealed‐disk assembly element. The Poisson distribution is used to perform the statistical and characterization analyses of the microcrack defects on the surface of Ni60/WC coating with the circular microdimples ablated by the nanosecond laser. The key process parameters of laser machining in groups with a high and a low ratio of apparent microcrack are selected, and are compared with the nontextured group on the coating surface through immersion–corrosion and electrochemical–corrosion tests. It finds the high and low apparent‐microcrack groups under the action of static corrosion, and the coating has the similar corrosion behavior with the nontextured group. When apparent microcrack does not extend to the substrate, the nanosecond‐laser ablation of microdimples does not change the coating corrosion properties. Moreover, the corrosion properties of the coating are improved by laser ablation recrystallization. The experimental support is provided in the results for the application of microdimples on the surface of fracturing‐pump plunger coating in acidic environments.
