“…This still poses the biggest issue and obstacle for the development of implants made of titanium alloy. A porous Ti-based alloy is regarded as a novel invention for the foreseeable future since it has been shown to encourage tissue regeneration and firmly secure implant by regulating the degree of sintering [148,213]. Moreover, the traditional powder metallurgy process can be enhanced using the self-propagating higher temperature synthesis (SHS) method of sintering [214,215].…”

Titanium and its alloys have already been widely used as implant materials due to their outstanding mechanical characteristics and biocompatibility. Notwithstanding this, researchers and businesses alike have continued to actively pursue superior alloys since there are still problems which need urgent consideration. One of these is a noteworthy difference in the implant material’s elastics modulus and that of natural bone, which result into an issue of stress shielding. With prolonged use Ti alloys releases dangerous ions. The Ti alloy surface has a low bioactivity, which prolongs the healing process. β-Ti alloys could be used as viable alternatives when creating dental implants. Additionally, β-Ti alloys characteristics, such as low Young modulus, increased strength, appropriate biocompatibility, and strong abrasion and corrosion resistance, serve as the necessary evidence. Ti alloys when altered structurally, chemically, and by thermomechanical treatment thereby enabling the creation of material which can match the requirements of a various clinical practise scenarios. Additional research is needed which can focused on identifying next century Ti alloys consisting of some more compatible phase and transforming the Ti alloys surface from intrinsically bioinert to bioactive to prevent different issues. In order to give scientific support for adopting β-Ti-based alloys as an alternative to cpTi, this paper evaluates the information currently available on the chemical, mechanical, biological, and electrochemical properties of key β-titanium alloys designed from the past few years. This article is also focusing on β-titanium alloy, its properties and performance over other type of titanium alloy such as α titanium alloys. However, in-vivo research is needed to evaluate novel β titanium alloys to support their use as cpTi alternatives.

“…Moreover, the processing of bulk tantalum is very difficult and expensive. 13 As Ta is non-toxic, it exhibits excellent biocompatibility in the human body, making it a promising implantable biomaterial for application in orthopedics. 14 In the orthopedic surgery, the implant infection has become one of the most important challenges in orthopedics.…”

“…However, tantalum nitride has recently attracted great interest as a protective coating due to its excellent properties such as good wear and corrosion resistance, super hardness, high strength and toughness (even at high temperatures), high thermal stability, and great thermal conductivity [4,[11][12][13]. These properties position this material as a great candidate for different applications such as diffusion barriers, an application in which it has achieved a great reputation [14,15], silicon-based integrated circuits, high-performance microprocessors and in a wide variety of biomedical applications, showing that these coatings have better histocompatibility and hemocompatibility than traditionally used biomedical alloys [16,17]. Additionally, the superconductor TaN has been shown to be a much better candidate than niobium nitride (NbN) for the detection of single photons [15] due to its smaller space and lower density of states.…”

Growth Mechanisms of TaN Thin Films Produced by DC Magnetron Sputtering on 304 Steel Substrates and Their Influence on the Corrosion Resistance

In this work, thin films of TaN were synthesized on 304 steel substrates using the reactive DC sputtering technique from a tantalum target in a nitrogen/argon atmosphere. All synthesis parameters such as gas ratio, pressure, gas flow, and substrate distance, among others, were fixed except the applied power of the source for different deposited coatings. The effect of the target power on the formation of the resulting phases and the microstructural and morphological characteristics was studied using XRD and AFM techniques, respectively, in order to understand the growth mechanisms. Phase, line profile, texture, and residual stress analysis were carried out from the X-ray diffraction patterns obtained. Atomic force microscopy analysis allowed us to obtain values for surface grain size and roughness which were related to growth mechanisms in accordance with XRD results. Results obtained showed a strong correlation between the growth energy with the crystallinity of the samples and the formation of the possible phases since the increase in the growth power caused the samples to evolve from an amorphous structure to a cubic monocrystalline structure. For all produced samples, the δ-TaN phase was observed despite the low N2 content used in the process (since for low N2 content it was expected to be possible to obtain films with α-Ta or hexagonal ε-TaN crystalline structure). In order to determine the corrosion resistance of the coatings, electrochemical impedance spectroscopy and polarization resistance were employed in the Tafel region. The results obtained through this evaluation showed a direct relationship between the power used and the improvement of the properties against corrosion for specific grain size values.
