Summary: This study investigates the influence of spraying potential on the phase composition, microstructure, hardness, wettability, and corrosion performance of amorphous coatings (ACs) deposited by arc-spraying technique. The results show that ACs with denser microstructure, higher microhardness, lower surface free energy exhibit better corrosion resistance. The corrosion resistance of the coatings is closely related to the surface hydrophobicity, which is mainly governed by the microstructure of the coatings.

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: Laser 3D printing was used to prepare two different types of amorphous coatings, and their morphology, amorphous content, and microstructure were investigated. The results showed that the coating deposited under air-cooled conditions had cracks on the surface, while the coatings with higher amorphous content exhibited higher hardness and corrosion resistance. Additionally, annealing treatment of the coatings reduced crack formation.

Summary: In this study, amorphous-nanocrystalline NiCr0.25Mox (x = 0, 0.02, 0.05, 0.1, 0.2, 0.4) alloy coatings for marine engineering equipment were developed via direct current magnetron sputtering. The relationship between the coating structure and performance, including composition, microstructure, corrosion resistance, and mechanical properties, was discussed in detail. The addition of Cr and Mo facilitated the formation of a dense passive film, alleviating grain boundary corrosion. The nanohardness and adhesion strength initially increased with Mo content but declined due to the formation of an amorphous phase. Notably, the NiCr0.25Mo0.1 coating exhibited superior corrosion resistance and mechanical behavior, attributed to the formation of a dense passivation film composed of Cr2O3 and Cr(OH)(3), which promoted homogeneous plastic deformation and inhibited crack propagation.

Summary: Fe-based amorphous coatings synthesized with Fe44Cr30Mo20B3C3 powders on Q235 substrate at different laser powers exhibit enhanced hardness and wear resistance. The synergistic effect between the amorphous phase and Cr23C6 contributes to the improvement of mechanical properties. The presence of Cr and the amorphous phase also enhances the passivation phenomenon and improves the corrosion resistance of the coatings.
