“…Due to the barrier effect caused both by the native TiO 2 layer and the newly formed TiN (or TiC), the diffusion process can take hours or even days before completion [ 403 ]. The required time can be reduced by using additional energy sources such as lasers [ 404 ], plasmas [ 405 ], or ultra-high frequency induction heating [ 406 ], but even optimized processes have limitations due to the increased surface roughness [ 407 ] and can act as a crack triggering point in fatigue conditions [ 408 ].…”

Titanium alloys have emerged as the most successful metallic material to ever be applied in the field of biomedical engineering. This comprehensive review covers the history of titanium in medicine, the properties of titanium and its alloys, the production technologies used to produce biomedical implants, and the most common uses for titanium and its alloys, ranging from orthopedic implants to dental prosthetics and cardiovascular devices. At the core of this success lies the combination of machinability, mechanical strength, biocompatibility, and corrosion resistance. This unique combination of useful traits has positioned titanium alloys as an indispensable material for biomedical engineering applications, enabling safer, more durable, and more efficient treatments for patients affected by various kinds of pathologies. This review takes an in-depth journey into the inherent properties that define titanium alloys and which of them are advantageous for biomedical use. It explores their production techniques and the fabrication methodologies that are utilized to machine them into their final shape. The biomedical applications of titanium alloys are then categorized and described in detail, focusing on which specific advantages titanium alloys are present when compared to other materials. This review not only captures the current state of the art, but also explores the future possibilities and limitations of titanium alloys applied in the biomedical field.

In order to fabricate a titanium alloy with superior wear resistance and fatigue strength, fine particle peening (FPP) was introduced as a post-treatment after gas blow induction heating (GBIH) nitriding. The surface characteristics of the treated alloy were examined using X-ray diffraction, scanning electron microscopy, laser microscopy and a micro-Vickers hardness tester. GBIH nitriding and post-treatment with FPP formed nitrided layers with high hardness and compressive residual stress at the surface of the alloy within a short period of time. This is due to the diffusion of nitrogen atoms during GBIH nitriding and plastic deformation of the surface layer during FPP. Reciprocating ball-on-disk wear tests were performed to investigate the wear resistance of the surface-treated alloy. The wear resistance of the titanium alloy was improved by the proposed surface treatment compared with samples that were only polished or FPP-treated. This is due to the presence of a nitrogen compound layer with high hardness at the surface. The abrasiveness toward the wear test counter material was also decreased by the combined surface treatment.

“…the gross slip regime). A variety of industrial assemblies, including aeroengine blade-disk dovetail joint (Miyoshi et al , 2003; Lemoine et al , 2020), prosthesis (Lanzutti et al , 2019) and coolant tube in nuclear power plant (Soria et al , 2019), are subjected to fretting wear because of the oscillatory movements induced by system vibration. The consequences of fretting wear conclude the material loss of components (Mary et al , 2011), the change of mating clearance and vibration characteristic (Lemoine et al , 2020), the leakage of pipelines (Soria et al , 2019) and so forth (Mary et al , 2011; Araujo et al , 2020).…”

Purpose Quantitative fretting wear prediction is of practical significance for industrial components. This study aims to establish a fretting wear model considering the formation of tribolayers and provide better fretting wear prediction. Design/methodology/approach Based on the characteristics for the formation of tribolayers, the ratio of fretting amplitude to nominal contact area length in the fretting direction is used to characterize their formation and contribution to the wear volume. The wear volume is then associated with the product of the friction energy and the ratio of fretting amplitude to nominal contact area length. Findings Better prediction in the wear volume can be achieved with the proposed fretting wear model by taking the formation of tribolayers into consideration. Originality/value The contribution of the formation of tribolayers to the wear volume is considered in the model and better prediction can be achieved.
