Titanium (Ti) and its alloy implants with porous structure manufactured by selective laser melting (SLM) can match elastic modulus of human bone to reduce the stress‐shielding effect and satisfy the personalized requirement in orthopedic surgery. Compared with conventional casting and forging Ti and its alloy implants, SLM implants possess unique microstructural features and excellent comprehensive mechanical properties. However, the un‐melted powder particles inevitably adhere to the surfaces of SLM implants, which may result in excessive surface roughness and potential health risks. Moreover, there are significant issues encountered, such as bioactivity, toxicity, antibacterial activity, corrosion and wear resistance. Consequently, surface modification methods are essential to remove the un‐melted powder particles and improve biological and mechanical properties of SLM implants. Herein, the research efforts focus exclusively on chemical (acid treatment, alkali treatment, sol‐gel, chemical vapor deposition and atomic layer deposition) and electrochemical methods (anodization and microarc oxidation) for SLM Ti and its alloy implants, especially for porous structures. Particularly, the characteristics of these methods are summarized, and their commonly used pre‐ and post‐treatment methods are introduced. In addition, the development trends and challenges in surface modification of SLM Ti and its alloy implants are discussed.This article is protected by copyright. All rights reserved.

“…17 Due to the above, methods of surface modification of metallic implants are being sought that would allow to fulfill these requirements, especially in the long-term aspect. The following methods that have already been used can be distinguished: plasma thermal spraying, 18 ion implantation, 19 plasma spraying, 20 magnetron sputtering, 21 physical vapor deposition, 22 chemical vapor deposition, 23 sol-gel, 24 micro-arc oxidation (MAO), [25][26][27][28] anodic oxidation (AO) [29][30][31][32] and electrophoretic deposition (EPD). [33][34][35][36] The last three abovementioned methods belong to the group of electrochemical methods, which are characterized by simplicity and a relatively low price compared to the rest of the mentioned methods.…”

Over the past decade, titanium implants have gained popularity as the number of performed implantation operations has significantly increased. There are a number of methods for modifying the surface of biomaterials, which are aimed at extending the life of titanium implants. The developments in this field in recent years have required a comprehensive discussion of all the properties of electrophoretically deposited coatings on titanium and its alloys, taking into account their bioactivity. The development that took place in this field in recent years required a comprehensive discussion of all the properties of coatings electrophoretically deposited on titanium and its alloys, with particular emphasis on their bioactivity. Herein, we attempt to assess the influence of the electrophoretic deposition (EPD) process parameters on these coatings' biological and mechanical properties. Particular attention has been addressed to the in‐vitro and in‐vivo studies conducted hitherto. We have seen an increased interest in using titanium alloys without the addition of toxic compounds and gaps in the EPD field such as the uncommon endeavors to develop a “Design of experiments” approach as well as the lack of assessment of the surface free energy and detailed topography of electrophoretically deposited coatings. The exact correlation of coating properties with EPD process parameters still seems explicitly not understood, necessitating more future investigations. Ipso facto, the exact mechanism of particle agglomeration and Hamaker's law need to be fathomable.

“…Ti-Mo-Nb alloys have been evaluated as an option for biomedical applications [ 27 , 28 , 29 , 30 , 31 , 32 ]. The study of Ti 10 Mo 3 Nb, Ti 10 Mo 7 Nb, and Ti 10 Mo 10 Nb alloys indicated a microstructure with equiaxial grains, a beta-phase in the alpha-matrix, and an increase in the content of the beta-phase with the increase in the concentration of niobium in the composition.…”

“…In general, zirconium and niobium favored a decrease in Young’s modulus and an increase in toughness and deformation. Therefore, our aim in the present study was to evaluate the influence of zirconium addition on the properties of the ternary system Ti 10 Mo 8 Nb previously evaluated by our group [ 31 , 32 , 43 ]. Mechanical and microstructural characterization was performed for the quaternary alloy Ti 10 Mo 8 Nb 6 Zr, and its potential for biomedical applications was evaluated.…”

The study of new metallic biomaterials for application in bone tissue repair has improved due to the increase in life expectancy and the aging of the world population. Titanium alloys are one of the main groups of biomaterials for these applications, and beta-type titanium alloys are more suitable for long-term bone implants. The objective of this work was to process and characterize a new Ti10Mo8Nb6Zr beta alloy. Alloy processing involves arc melting, heat treatment, and cold forging. The characterization techniques used in this study were X-ray fluorescence spectroscopy, X-ray diffraction, differential scanning calorimetry, optical microscopy, microhardness measurements, and pulse excitation technique. In vitro studies using adipose-derived stem cells (ADSC) were performed to evaluate the cytotoxicity and cell viability after 1, 4, and 7 days. The results showed that the main phase during the processing route was the beta phase. At the end of processing, the alloy showed beta phase, equiaxed grains with an average size of 228.7 µm, and low Young’s modulus (83 GPa). In vitro studies revealed non-cytotoxicity and superior cell viability compared to CP Ti. The addition of zirconium led to a decrease in the beta-transus temperature and Young’s modulus and improved the biocompatibility of the alloy. Therefore, the Ti10Mo8Nb6Zr alloy is a promising candidate for application in the biomedical field.
