“…The surface of the specimen, as well as the spontaneously formed oxide film (i.e., TiO 2 ) of the titanium alloy, would not be very flat. [ 47 ] Therefore, the thickness of the oxide film ( d film ) formed on selective laser‐melted Ti6Al4V–5Cu alloy and forged TC4 specimens can be calculated by [ 47 ] :

d_{f i l m} = \frac{ε ε_{0} A}{C_{normale normalf normalf}},

where ε, ε 0 , A , and C eff denote the permittivity of vacuum (i.e., 8.85 × 10 −14 F/m), the dielectric constant of the oxide (e,g., TiO 2 is 60 [ 48 ] ), the effective surface area (m 2 ), and the effective capacitance, that is, the CPE value from EIS fitting result. The calculated thickness of the oxide film formed on the selective laser‐melted Ti6Al4V–5Cu alloy and forged TC4 specimens was estimated to be 0.162 and 0.123 nm, respectively.…”

Ti6Al4V-5Cu alloys have potential biomedical applications due to their adequate antibacterial properties. However, the wear and corrosion properties of these alloys are also crucial for dental implants. In the present study, Ti6Al4V-5Cu alloys were fabricated by selective laser melting (SLM). The microstructure and composition of Ti6Al4V-5Cu alloys by SLM were evaluated. The wear properties of the alloys in the simulated saliva environment and the atmospheric environment, as well as the electrochemical properties in the simulated saliva environment, were systematically investigated. The results showed that the crystal structure of Ti6Al4V-5Cu alloys was mainly composed of α-Ti and Ti 2 Cu. In the SLM process, no preferred texture was observed due to the complex direction of the heat flux. The formation of Ti 2 Cu can improve the strength of the material and make the titanium copper alloy have higher microhardness. Ti6Al4V-5Cu alloy showed a satisfactory wear resistance in both wear media. The addition of Cu reduced the second-phase content of the alloy. Meanwhile, the number of microcells was reduced, which was a positive factor to improve the corrosion resistance of the alloys.

“…Creation of a large amount of Q when added to Ti, Cu is also a viable candidate for designing Ti-based alloys by the AM process. Hence, Ti-Cu alloys have been investigated using Laser Powder Bed Fusion (LPBF) [45,46] and DED [29] methods. As outlined in Equation ( 1), copper with a maximum solubility of 17 wt.% in β-phase titanium can create a Q as high as 110.5 when added to Ti, given the fact that m•(k − 1) = 6.5 K for this alloy [29].…”

Metal additive manufacturing (AM) is an innovative manufacturing method with numerous metallurgical benefits, including fine and hierarchical microstructures and enhanced mechanical properties, thanks to the utilization of a local heat source and the rapid solidification nature of the process. High levels of productivity, together with the ability to produce complex geometries and large components, have added to the versatile applicability of metal AM with applications already implemented in various sectors such as medicine, transportation, and aerospace. To further enhance the potential benefits of AM in the context of small- to medium-scale bulk production, metallurgical complexities should be determined and investigated. Hence, this review paper focuses on three significant metallurgical aspects of metal AM processes: in situ alloying, functionally graded materials, and surface treatments for AM parts. The current text is expected to offer insights for future research works on metal AM to expand its potential applications in various advanced manufacturing sectors.

“…Titanium alloys are extensively applied in the aerospace, petrochemical, metallurgical, papermaking and medical industries due to their low density, high specific strength, favorable corrosion resistance and low costs [1][2][3][4]. When they operate under salt-containing service environments (such as boiler tubes in waste incinerators and engine components), chlorides-rich salt deposits inevitably condensate on the alloy materials.…”

TiN and TiAlN coatings were deposited by arc ion plating on titanium alloys to study their hot corrosion resistance when they were exposed to NaCl at 600 °C. The microstructure and corrosion behaviors of nitride coatings were studied using scanning electron microscope, X-ray diffraction, electro-probe microanalyzer and X-ray photoelectron spectroscopy. The results showed that nitride coatings with the different compositions and the ones with the same composition but different thicknesses presented different hot corrosion resistance. TiN and thin TiAlN coatings showed poor corrosion resistance. Serious internal oxidation attacked the alloy substrate. Their corrosion products were mainly consisted of non-protective TiO 2 and sodium salt. By contrast, the thick TiAlN coating presented outstanding corrosion resistance. Besides sodium salt, the corrosion products were composed of protective Al 2 O 3 . The increasing thickness of TiAlN significantly enhanced the hot corrosion resistance. The corrosion mechanisms of alloy, TiN and TiAlN coatings were discussed in detail.
