“…In addition, the stability of the emulsion, corrosion resistance and thermal stability of the resin coating are significantly enhanced. With the significant applications of metals and alloys [57][58][59][60][61][62][63][64][65][66] and the awareness of corrosion [67][68][69][70], the modified waterborne acrylic resin with its excellent water resistance will have a potential application prospect in the fields of waterproof and anticorrosive coating of metals.…”

“…There were some research about the NiTi-based scaffolds to overcoming the challenge through the coating preparation. Guo et al [175] reported that the preparation of graphene oxide coating on the NiTi SMAs benefited to the corrosion resistance, inhibiting the release of Ni ions, as well as the facilitation of the adhesion, growth, and proliferation of osteoblasts. Similarly, they prepared a bioactive dicalcium phosphate dihydrate (DCPD) coating on the LPBF-NiTi alloys via electrodeposition to improve the corrosion resistance and biocompatibility of the LPBF-NiTi [176].…”

NiTi alloys have drawn significant attention in biomedical and aerospace fields due to their unique shape memory effect (SME), superelasticity (SE), damping characteristics, high corrosion resistance, and good biocompatibility. Because of the unsatisfying processabilities and manufacturing requirements of complex NiTi components, additive manufacturing technology, especially laser powder bed fusion (LPBF), is appropriate for fabricating NiTi products. This paper comprehensively summarizes recent research on the NiTi alloys fabricated by LPBF, including printability, microstructural characteristics, phase transformation behaviors, lattice structures, and applications. Process parameters and microstructural features mainly influence the printability of LPBF-processed NiTi alloys. The phase transformation behaviors between austenite and martensite phases, phase transformation temperatures, and an overview of the influencing factors are summarized in this paper. This paper provides a comprehensive review of the mechanical properties with unique strain-stress responses are also explained, which comprise tensile mechanical properties, thermomechanical properties (e.g., critical stress to induce martensite transformation, thermo-recoverable strain, and superelasticity strain), damping properties and hardness. Moreover, several common structures (e.g., a negative Poisson’s ratio structure and a diamond-like structure) are considered, and the corresponding studies are summarized. It illustrates the various fields of application, including biological scaffolds, shock absorbers, and driving devices. In the end, the paper concludes with the main achievements from the recent studies and puts forward the limitations and development tendencies in the future.

“…[20] Besides, the impermeability of GO can prevent the attack of corrosive liquid, significantly enhancing the corrosion resistance of the matrix materials. [21,22] To this day, numerous studies have been conducted on GO-reinforced Ti matrix composites fabricated by LPBF. M. Li et al studied the effect of adding GO on the properties of Ti alloy and found that GO can improve the nanohardness of the material and refine the grain.…”

As a high‐efficiency laser additive manufacturing technology, laser powder bed fusion (LPBF) has unparalleled advantages in the manufacture of titanium matrix composites. In this work, the effect of laser energy density (LED) on the forming quality, microstructure evolution, and corrosion resistance of LPBF‐fabricated nanographene oxide reinforced titanium matrix nanocomposites (GO/TC4) was investigated. The results show that the optimal surface roughness and relative density of GO/TC4 nanocomposites fabricated by LPBF are 11.8 μm and 99.40%, respectively. The microstructure is mainly acicular α/α′‐Ti, accompanied by a small amount of β‐phase grain boundaries. When the LED is increased to 58.33 J/mm3, the self‐corrosion potential of GO/TC4 sample reaches 0.345 V in 3.5 wt% NaCl solution, and the GO/TC458.33 nanocomposite exhibits the highest corrosion resistance. The results revealed that the corrosion products on the surface of the samples were mainly composed of a passivation film of TiO2 and a small amount of Al2O3.
