Titanium and its alloys are potential materials for orthopedic implant applications due to their appropriate biological and mechanical behavior. As biocompatibility and biomechanical compatibilities are essential parameters for determining a biomedical implant's performance and service life, this research review article discussed the novel Ti alloys with nontoxic and biocompatible alloying elements with an elastic modulus similar to the bone. Among Ti alloys, β-Ti alloys are appropriate for load-bearing implant applications due to lower elastic modulus and nontoxic elements, including Ti, Ta, Nb, Zr, Sn, and Mo. Even though the β-Ti alloys possess a lesser elastic modulus compared to other metallic biomaterials, two issues associated with β-Ti alloys that result in implant failure are that they still possess a higher elastic modulus than human bone and they have insufficient strength. Alloy composition and thermomechanical processing characteristics play a vital role in altering the mechanical properties and microstructure of β-Ti alloys. Hence, this review article emphasizes the alloying and thermomechanical processing effects on the mechanical properties and microstructure of β-Ti alloys.

“…Then it disproportionates with the formation of boric anhydride B 2 O 3 and atomic boron, which diffuses through the interface into titanium and forms the chemical compound TiB on the surface. Under such conditions of boriding, the internal energy of oxygen is sufficient for overcoming the energy barrier, dissolution into titanium, and formation of a solid solution Ti(O) (diffusion layer) [39,42].…”

The surface characteristics and friction behaviour of titanium Grade 2 with modified nitride (TiN, Ti2N) and boride (TiB) compound layers were investigated. It was shown that during non-contact boriding in oxygen-containing medium of titanium, the diffusion processes take place mainly by the interscale mechanism; however, during nitriding, besides the traditional interscale diffusion mechanism, the grain boundary mechanism of diffusion of nitrogen atoms is also realized. The optimal set of surface roughness parameters (height and step parameters, a combination of kurtosis and asymmetry, and profile reference curve parameters) was obtained after boriding. It was determined that the intensity of the adhesive wear of the tribo-pairs with stainless steel and ultrahigh molecular weight polyethylene under dry sliding conditions was influenced not only by the hardness but also roughness of the modified surface layer. The lowest friction coefficient was fixed for the TiB compound layer in both tribo-pairs.

“…Titanium already forms an oxide layer at low temperatures, which has a passivating effect and thus prevents further oxidation of the titanium. However, at temperatures above 500 °C, the oxidation resistance decreases significantly, so that titanium has a much higher solubility for foreign elements such as O, N, C and H, which can change the material properties [32,33]. These interstitially dissolved atoms and reaction products significantly affect the microstructure of titanium and its mechanical properties.…”

Titanium and titanium alloys have high strength at low density, good corrosion resistance and excellent biocompatibility. Therefore, the use of titanium materials is well established in high-performance applications such as aerospace and biomedical. However, titanium and titanium alloys such as Ti–6Al–4 V have low thermal conductivity, exhibit unfavorable chip formation with typical segmented chips and have high chemical affinity to surrounding elements such as oxygen. Tool wear and the properties of the component surface and sub-surface are significantly influenced by the presence of oxygen and resulting chemical interactions. Among other things, chemical reactions such as oxidation occur due to the high temperatures and presence of oxygen. In this work, the chip formation of Ti–6Al–4 V at different cutting speeds in discontinuous orthogonal cutting process under different atmospheres is investigated. A conventional air atmosphere, a pure argon atmosphere and a silane-doped atmosphere were used. The oxygen content of the silane-doped argon atmosphere corresponds to an extremely high vacuum (XHV), which is practically oxygen-free. It was found that chip formation is affected by the surrounding atmosphere. At the cutting speed vc = 80 m/min, non-periodic segmentation is present under oxygen-free atmosphere, while segmental chip formation occurs under air. This is accompanied by up to 16.5% lower feed force under inert gas atmosphere, which is due to reduced friction caused by the use of an oxygen-free atmosphere.
