“…Due to the integrated computer-aided design software with the laser system equipment, a wide variety of geometrical shape disclosure can be applied for microstructuring, allowing different patterns to be designed without difficulty. Until now, the most used pattern designs were dimple/hole/crater array [41][42][43][44][45][46][47][48][49], parallel lines [50][51][52][53][54][55][56][57][58][59][60], meshed or cross-pattern [48,53,55,[60][61][62][63]. The outstanding pattern designs were square [49,57,62], triangle [62], coral-rock and star-like [64], single ellipse [39,65,66], lotus leaf-like [52], prominent structures [67], octagons [39], and Siberian-Cocklebur-like [34].…”

Due to its wide applicability in industry, devising microstructures on the surface of materials can be easily implemented and automated in technological processes. Laser Surface Texturing (LST) is applied to modify the chemical composition, morphology, and roughness of surfaces (wettability), cleaning (remove contaminants), reducing internal stresses of metals (hardening, tempering), surface energy (polymers, metals), increasing the adhesion (hybrid joining, bioengineering) and decreasing the growth of pathogenic bacteria (bioengineering). This paper is a continuation and extension of our previous studies in laser-assisted texturing of surfaces. Three different patterns (crater array-type C, two ellipses at 90° overlapping with its mirror-type B and 3 concentric octagons-type A) were applied with a nanosecond pulsed laser (active medium Nd: Fiber Diode-pumped) on the surface of a ferritic stainless steel (AISI 430). Micro texturing the surface of a material can modify its wettability behavior. A hydrophobic surface (contact angle greater than 90°) was obtained with different variations depending on the parameters. The analysis performed in this research (surface roughness, wettability) is critical for assessing the surface functionality, characteristics and properties of the stainless steel surface after the LST process. The values of the surface roughness and the contact angle are directly proportional to the number of repetitions and inversely proportional to the speed. Recommendations for the use of different texturing pattern designs are also made.

“…The scan velocity, laser power, and strategy during the laser processing greatly control the texture line and surface roughness. The energy density of a fiber laser depends on scan velocity and laser power [9]. Figures 5 and 6 show that the error bar was slightly different.…”

“…Fiber lasers offer a flexible solution, effective pulse repetition rates, and fast processing times with sufficient results for texturing various materials with varying surface patterning. The laser energy density of fiber lasers can be controlled by modulating the laser power and scanning speed to obtain an ideal surface patterning [8,9]. Materials and laser interaction can produce micro or nano-structures, including ripples, nanoparticles, and other structures [10].…”

We present a fast, straightforward fabrication method to produce stable superhydrophobic copper alloy surfaces. The technique consists of irradiating copper with a fiber laser and then coating the surface with ethanol. The laser ablation generates surface morphology on the copper surfaces, such as line and grid patterns. We can modify the wetting properties and surface morphology by changing the step size. We assessed the change of the water contact angle on the raw surface, laser-based textures after natural aging, and laser-based textures post-low annealing. After that, we measured the stability of the water contact angle till 120 days. After low annealing heat treatment, water contact angles on grid pattern surfaces have superhydrophobic surfaces and are more stable till 120 days.

“…It can influence the surface roughness [16], produce severe surface damage, as well as modifications in the microstructure or in the composition of the ceramic material [17]. It must be noted that LBM is also increasingly used to texture metallic components [18] and cutting tools [16]. The heat-affected zone (HAZ) generated by a nanosecond laser beam is characterised by micro-cracks, remelted material or recrystallisation [17].…”

The innovative Green Ceramic Hybrid Machining (GCHM) process sequentially combines milling with a cutting tool (GCM, Green Ceramic Machining) and laser beam machining (GCLBM) of a ceramic material (black Y-TZP in this study) at the green stage mainly to increase productivity, avoid taper angle limitations of laser beam machining, and obtain micro-features. The study focuses on the reliability and the repeatability of the properties of sintered parts obtained by three manufacturing processes (GCM, GCLBM, GCHM) to assess the performance of hybridisation. It turns out that GCHM is a compromise of both milling and laser beam processes; it increases the repeatability of the surface quality and it slightly reduces (less than 7%) the flexural strength by comparison to milling for a similar reliability. The study also highlights that the surface quality of GCLBM processed parts relies on of the surface generated by the previous operation. Milling that surface at the previous step is therefore recommended, corresponding to the sequence adopted by GCHM.
