“…The Ti intermediate layer enhances the reaction (Equation ) compared with the single layer TiN coating but the exact mechanism requires further study. The potential of TiAl 6 V 4 substrate increases initially and then decreases revealing that formation and dissolution of the native oxide layer (mainly TiO 2 ) reaches equilibrium after approximately 60 s. The results suggest that surface oxide layer is initially dissolved by aggressive ions before equilibrium and dissolution of the oxide layer proceeds as follows:

{normalH}_{2} normalO + Ti {normalO}_{2} + {normalH}^{+} \to Ti {(OH)}_{3}^{+}

To improve the corrosion properties of TiAl6V4 alloy, TiN monolayer and Ti/TiN multilayer coatings are deposited by reactive magnetron sputtering. The phase, structure, and morphology properties are investigated by grazing‐incidence X‐ray diffraction, field‐emission scanning electron microscopy, and atomic force microscopy, respectively, and the corrosion behavior is evaluated by electrochemical impedance spectroscopy and potentiodynamic polarization. The TiN monolayer and Ti/TiN multilayer with thickness of 1,350 and 1,410 nm have the (111) and (002) preferred orientation and crystallite size of 42.5 and 24.3 nm, respectively. Columnar growth in TiN is hindered by the Ti interlayers and no cracking is observed between the layers indicating strong adhesion. The nanostructured Ti/TiN coating forms stable surface titanium oxide which improves the corrosion resistance by approximately 80 and four times compared with TiAl6V4 alloy and TiN coating, respectively. Hindrance of the columnar structure in TiN by the Ti interlayer decreases the local corrosion rate and enhances the galvanic corrosion resistance by forming a layer on the β‐phase enriched with vanadium as well as a TiO2 stable layer. The nanostructured Ti/TiN coating demonstrates capacitive behavior with phase angles approximately −50° and high impedance values at low frequency to be the corrosion resistance mechanism.

“…This paper follows on from the prior study, and aims to assess the corrosion behavior of porous Ti35Zr28Nb compared with porous commercial‐purity CP Ti Grade 2, under crevice corrosion conditions, in Hanks’ solution at 37 °C and 3.5 wt% NaCl solution at 95 °C. Hanks’ solution simulates medical implant conditions, while the 3.5 wt% NaCl solution provides much more aggressive conditions.…”

The present research examined the corrosion and crevice corrosion behavior of porous specimens of Ti35Zr28Nb and CP Ti in Hanks’ solution at 37 °C and in 3.5 wt% NaCl at 95 °C. The following conclusions can be drawn. There was no crevice corrosion for porous specimens of Ti35Zr28Nb and CP Ti in Hanks’ solution at 37 °C and in 3.5 wt% NaCl at 95 °C. Both alloys had low corrosion rates in both solutions, and both alloys were passive in both solutions.

“…The fabricated alloy also exhibits excellent mechanical properties of trabecular bone with the elastic modulus (0.2-5) GPa and compressive strength (4-70) MPa. Whereas [17][18][19] performed an experimental investigation on the corrosion behavior of Ti35Zr28Nb in Hanks' solution at 37 °C and 3.5 wt% NaCl solution at 95 °C. These investigations indicate that there was no evidence of crevice corrosion under various conditions.…”

Additive manufacturing (also known as 3D printing) process is an emerging technique for the fabrication of biomedical components. Selective laser sintering or melting is one of the widely used additive printing technology for manufacturing of metallic and non-metallic components used in the industry. This review paper presents, a summary of the published research papers on the fabrication of biomedical components using selective laser sintering technique. Therefore, author meticulously attempted to investigate individual biocompatible material-wise review which includes Ti6Al4V, Ti-7.5 Mo alloy, β-Ti35Zr28Nb, PEEK, PA2200, and Polyamide/Hydroxyapatite. In addition, this article also explores the effects of the various laser sintering process parameters such as laser power, scanning speed, density of the material on the mechanical properties, tribological properties, porosity and surface roughness of the fabricated alloy. Moreover, the author also investigated challenges and future prospective of the laser processing of biomedical implants.
