Results showed that higher scanning speeds led to smoother coatings, reduced residual stress, and improved thermal expansion coefficients. At a scanning speed of 80.38 m/min, the coating exhibited better performance with lower residual tensile stress.

Summary: High-speed laser cladding (HLC) technology reduces heat input to the substrate surface by changing the convergence point of the laser beam and powder stream. HLC coatings have faster cooling rates compared to conventional laser cladding (CLC), resulting in coatings with low dilution and high amorphous content. A study comparing Fe-based amorphous coatings deposited on AISI 1020 seamless steel tubes using CLC and HLC processes found that the HLC coating had a more uniform distribution of amorphous phases, smaller and denser microstructure, and better corrosion resistance than the CLC coating. The mechanical properties and corrosion resistance of the coatings improved with increasing amorphous phase content.

Summary: WC/Ni composite coating prepared by laser cladding can be used to repair worn areas on the surface of cold work dies. The coating is composed of M23C6, FeNi3, Cr7C3, WC, W2C, Cr2B, Fe2B, and W2B. Changes in scanning speed have little effect on the internal structure and strengthening mechanism of the coating. Decreasing the scanning speed increases the powder deposition density and leads to brittle fracture of the coating.

Summary: The Fe-Cr-Mo-B-C coating was prepared on 45 steel using laser cladding. The effects of different process parameters on the properties of the coatings were analyzed. The increase of laser power or overlap rate resulted in more serious crystallization, porosity, and even cracks, reducing the overall properties of the coatings. The microhardness of the coatings was determined by the amorphous phase and hard phases B6Fe23 and Cr2B. The optimal conditions for laser cladding were identified as a power of 1400 W with an overlap rate of 30%.

Summary: The effects of scanning speed on the microstructure and wear behaviors of TiC and Ni60 coatings on Ti6Al4V alloy were investigated. The results showed that the scanning speed had an influence on the clad height, width, and depth, as well as the distribution and morphology of TiC particles in the coatings. The hardness of the coatings decreased with increasing scanning speed, while the weight loss increased. This was attributed to the presence of TiC particles in the coatings, which enhanced the wear resistance properties.

Summary: In this study, the quench sensitivity of TiB2/7050Al composite was investigated using Jominy end quench test. It was found that the hardness decreased significantly with increasing distance from the quenching end, as more eta phases precipitated and coarsened on grain boundaries. The composite was observed to be more quench sensitive than its alloy counterpart, attributed to four microstructure characteristics inherited from the aluminum matrix and originating from the TiB2 addition.

Summary: The study fabricated a near full-dense hierarchical CrCoNi medium entropy alloy (MEA) using selective laser melting (SLM), achieving superior yield strength at 77K. The high strength of the material stems from a hierarchical microstructure composed of high-density dislocations and low-angle grain boundaries (LAGB). The results suggest that SLM is a viable technique for fabricating dense hierarchical CrCoNi MEA and offer a design strategy to further improve mechanical properties.

Liquid vortex plays a crucial role in the formation of macropores and complex fluid dynamics on mountain-like microstructures can cause the formation of CCLIPSS. This opens up new possibilities to diversify the morphologies of LIPSS formed by femtosecond laser ablation in liquid.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
