“…When the scanning velocity is low, such as 100 μm s −1 , the laser pulse spot overlap rate and the number of laser pulses irradiated during a single scan are greatest. Therefore, the interaction time between the beam and the material and the number of laser irradiation pulses per unit time and unit distance will be the highest, and this will ablate the material deeply [46]. As scanning velocity increases, the laser spot pulse overlap rate and the number of laser pulses decreases.…”

“…As scanning velocity increases, the laser spot pulse overlap rate and the number of laser pulses decreases. The interaction time and the number of laser irradiation pulses per unit time and unit distance will reduce, and the depth of the ablation will also reduce [46]. The importance of these parameters for ablation depths is that they can be controlled so that the feed rate for the ablation rate can be adjusted during laser processing, to improve the precision of the ultrafast pulsed laser processing of the materials.…”

“…So, when the scanning velocity is 100 mm s −1 , the equivalent ablation time by the beam on the material will be the highest, and this will result in heat accumulation hence the threshold fluence is lowered. Because of reduced threshold fluence, the laser beam will ablate the material deeply [46]. As a result, material removal will be the highest, which translates to high ablation rates and efficiency.…”

Monel® alloy 400 has excellent corrosion resistance and finds applications in marine industries. The processing of marine components requires high processing efficiency and a quality finish. Hence, this research aims to investigate the effects of the laser processing parameters such as laser fluence, scanning velocity, hatching distance, and the scanning pass on the ablation rates and efficiency, chemistry, and nanomechanical properties of the Monel® alloy 400 after pulsed picosecond (ps) laser ablation. From the experimental findings, the ablation depth increases as the laser fluence increases while decreasing as the scanning velocity increases. Surface roughness was noted to increase as the laser fluence increased. The findings demonstrated that the ablation rate increases as laser fluence increases while ablation efficiency decreases. Energy dispersive X-ray spectroscopy (EDX) showed that the elemental composition of laser-ablated zones is almost similar to that of the polished sample. X-ray spectroscopy (XPS) shows that the outer layer on the surface of Monel® alloy 400 is composed of NiO and CuO. The hardness and Young’s modulus of the laser-processed alloy were found to be less than those of the bulk material. This study can be used to establish optimal processing parameters for the ultrafast ps laser processing of materials to achieve high ablation efficiency with a high-quality surface finish for industrial applications.

In this experimental study, picosecond laser treatment was performed on a nickel-based superalloy Nimonic 263, aiming to investigate the surface effects induced by irradiation in different atmospheric conditions and, concerning changes in surface composition, regarding the possibility for improvement of its functionality. Besides the varying laser parameters, such as a number of pulses and pulse energy, environmental conditions are also varied. All surface modifications were carried out in standard laboratory conditions and a nitrogen- and argon-rich atmosphere. The resulting topography effects depend on the specific laser treatment and could be categorized as increased roughness, crater formation, and formation of the laser-induced periodic surface structures (LIPSS). Changes in the chemical surface composition are distinguished as the potential formation of the protective oxides/nitrides on the sample surface. Numerous characterization techniques analyse the resulting effects on the topography and surface parameters. The multi-response parametric optimization of the picosecond laser process was performed using an advanced statistical method based on Taguchi’s robust parameter design. Finally, the optimal parameter conditions for Nimonic 263 modification are suggested.

“…[6][7][8][9][10] Surface modification techniques such as thermal deposition, electro-deposition, and mechanical coating help to reduce the material removal due to wear. [11][12][13] But these techniques have their demerits, such as the requirement for external energy supply, the surface finish of coating, and the production of fumes and radiation, which are harmful to the human body. It is discovered that each of these elements has a negative impact on the ecosystem.…”

Thrust plate in an external gear pump is one of the most important element which aligns the rotating gears and prevents the leakage through lateral clearances between rotating and non-rotating surfaces. It acts as a sacrificing element and fails frequently under fluctuating load pressure condition. The present research aims at enhancing the relative mechanical and tribological properties of the sacrificial thrust plate through electroless Ni-Mo-P coatings. Molybdenum (Mo) concentration in the electroless bath were tested for their effects on surface morphology, hardness, phase formation, wear rate, and wettability. A hard and self-lubricating layer (Al, Ni, Si, and Mo phases) on the coated surface was indicated by the compositional analysis performed using EDS and XRD. Results show that the microhardness of the coated surfaces has increased significantly by 149.5% (maximum hardness ~ 183.45 HV0.2) for 32 g L−1 Mo concentration. With 32 g L−1 Mo, the maximum coating thickness and water contact angle were 58 µm and 111°, respectively. The base material’s coefficient of friction was 0.5, whereas it was 0.25, 0.10, 0.06, and 0.03 for the samples made with 8, 16, 24, and 32 g L−1 Mo concentration, respectively. Compared to the uncoated sample, the maximum decrement in corrosion rate was found to be about six to seven times in the coated sample (with 32 g L−1 Mo). As a result, the developed coating surfaces provide hardness, lubricity, hydrophobicity, corrosion, and wear resistance simultaneously. The methodology of surface treatment can be used to modify the surface of critical hydraulic components having significant wear like in case of hydraulic cylinders.
