Summary: This paper proposes a method using laser treatment for protecting steel surface against electrochemical corrosion. AISI 430 stainless steel plates were used in the experiment. The influence of laser structuring on contact angle and the interaction between laser-structured steel surfaces and aggressive environment during corrosion tests were studied. The composition of oxides formed after laser treatment and the roughness of the modified surface were also considered. Positive results in protection against pitting corrosion formation on metal surfaces were revealed.

Summary: Laser polishing and water jet assisted recirculating shot peening can improve the surface quality, microstructure, and electrochemical properties of AISI316L stainless steel components. Laser polished samples had a smooth surface with high tensile residual stress, while shot peened samples exhibited higher surface hardness and compressive residual stress, and had a wider passive range in cyclic potentiodynamic polarization measurements, higher polarization resistance in electrochemical impedance spectroscopy measurements, and less defective passive film in Mott-Schottky analysis.

Summary: Plasma nitriding was conducted to enhance the strength and corrosion resistance of LAM 18Ni300 maraging steel. The nitrided surface showed a heterogeneous structure consisting of LAM dendrite boundaries and nanosized N-rich grains and associated N-depleted grains, which improve pitting resistance. The corrosion reaction on the nitrided surface is confirmed as gamma '/gamma + O -> MeO(N) + Me+, (Me = Fe, Co, Ni, Mo).

Summary: This study explored the feasibility of direct coating of steel surfaces treated with continuous-wave laser (CWL) and compared the adhesion and corrosion resistance of the coatings with those of surfaces treated with molten alumina blasting. The study found that CWL-treated surfaces provided better coating adhesion but reduced corrosion resistance. It is recommended to blast CWL-treated surfaces before coating to improve durability and corrosion resistance.

Summary: Laser-induced periodic surface structures (LIPSS) have great potential in regenerative biomedicine for creating biomimetic implant surfaces with improved properties. In this study, stainless steel samples were treated with a picosecond laser system to create linear LIPSS patterns with grooves. The laser-treated surfaces demonstrated higher surface roughness, good biocompatibility, lower wettability, and higher corrosion resistance compared to untreated samples. The microscale surface roughness enabled the adhesion and migration of endothelial cells, reducing the chances of late stent thrombosis and in-stent restenosis. Furthermore, the laser-textured surfaces provided an environment supportive of cell attachment, proliferation, and alignment with nanogrooves, helping to overcome post-surgery complications after stent implantation.

Summary: This study investigates the effect of laser polishing (LP) on the corrosion performance of S136 steel and compares it with mechanical polishing (MP). The results demonstrate that LP significantly improves the corrosion performance of S136 steel by increasing the presence of Cr2O3 in the passive film, forming a melting layer, and reducing non-metallic inclusions on the surface.

Summary: The LPBF process results in a significantly refined microstructure and more uniform distribution of principal phases for the high-strength Fe85Cr4Mo8V2C1 tool steel, leading to reduced corrosion activity in more aggressive environments. Additionally, LPBF samples exhibit a wave-like corrosion pattern due to microstructural features related to melt tracks.

Summary: The influences of laser shock peening (LSP) with different coverage layers on the electrochemical and long-term immersion corrosion behaviors of 2Cr12NiMoWV martensitic stainless steel in 3.5 wt% NaCl solution were studied. LSP-induced corrosion resistant surface resulted in significant diminution of corrosion density and passive current density, as well as higher pitting potential. LSP-generated carbide decomposition, matrix nanocrystallization and surface segregation of Cr contributed to the generation of Cr-rich passive film with better corrosion resistance. Due to the inhibitory effect of matrix nanocrystallization and compressive residual stress on corrosion propagation, LSP greatly reduced the size and number of the corrosion pits even after 30 days' immersion in NaCl solution.

Summary: A thick cementite skeleton exposed on a ferritic-pearlitic C1018 steel surface significantly reduced inhibition efficiency after pre-corrosion, while this effect was insignificant for a lower carbon X65 steel with dispersed cementite microstructure, as only a small amount of cementite remained on its surface after pre-corrosion. Normalizing the increased cathodic area in the presence of residual cementite back to the original area inhibited both anodic and cathodic reactions to the same extent as on bare steel with a sufficient inhibitor concentration. However, the detrimental effect of cementite cannot be completely eliminated due to its galvanic coupling effect.

Summary: This study computationally investigated the erosion characteristics of stainless steel 316 in a water-submerged jet impingement setup, analyzing the effects of various parameters on erosion and validating the computational model. Results show that material thickness loss increases with increasing jet velocity, as expected, but increasing nozzle diameter reduces the depth of erosion. Factors such as separation distance, nozzle shape aspect ratio, and impingement angle affect the maximum thickness loss and erosion pattern.

Summary: Light beams possess three types of angular momentum, namely spin angular momentum, extrinsic orbital angular momentum, and intrinsic orbital angular momentum. The interaction between these momenta leads to the spin-orbit interaction of light and topological effects. This study predicts a new topological effect resulting from the influence of extrinsic orbital angular momentum on spin angular momentum in converging asymmetrical light beams. It manifests as the transformation of linear polarized light into elliptically polarized light when an asymmetrical beam passes through the left or right half of the focal plane. The measured value of the topological circular amplitude anisotropy R was found to be R = +/- (0.60 +/- 0.08) x 10(-3). This new effect contributes to our understanding of light and has potential applications in developing sensors in optics.

Summary: Due to the complexity of resolving object form and pose in images, new vision algorithms prioritize identification and perception over accurate coordinate measurement. However, the use of planar targets for coordinate measurement in vision systems has several drawbacks, including calibration difficulties and limited viewing angles. On the other hand, the use of sphere targets is infrequent in vision-based coordinate metrology due to the lack of efficient multi-view vision algorithms for accurate sphere measurements.
