“…[ 153 ] Furthermore, annealing heat treatment is usually used after anodization, which can transform the amorphous TiO 2 nanotubes into crystalline TiO 2 nanotubes (anatase and/or rutile), which is beneficial for apatite formation. [ 204 ] Especially, the combination of nanotubes and crystal structure accelerates the deposition of HA coating and improves the adhesion strength between TiO 2 nanotubes and substrate. [ 153 ] Meanwhile, the water contact angle is reduced, and a superhydrophilic surface is formed to promote the protein adsorption and cell adhesion.…”

“…[137,205] The effects of preheat treatment (950 °C heat treatment) and post-heat treatment (500 °C annealing) on the surface morphology, phase composition, and structural size of TiO 2 nanotubes on SLM Ti6Al4V alloy were studied. [204] As shown in Figure 14, TiO 2 nanotubes of as-printed (AS) sample were orderly and evenly arranged as α and α 0 phases have the same phase structure. In comparison, TiO 2 nanotubes of preheat treatment (AS þ AN) sample showed significant fracturing of the nanotube layer due to their phase transformation.…”

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.

“…Laser-based additive manufacturing (LAM) are AM processes, which utilizes laser source as the heat source and laser beam to rapidly melt metal powder. LAM is used in various industries like biomedical [69][70][71][72][73], aerospace [74,75] and tool-making [76]. LAM gains some advantages over the conventional machining and powder metallurgy techniques.…”

“…Antibacterial drug loading into the porous structure of titania nanotubes (TNTs) allows sufficient drug loading and subsequent release on the surgical local site. This approach remained a key strategy to minimize or mitigate the implant infection problem [ 10 , 11 ]. Recently, Kunrath et al [ 12 ] and Kunrath et al [ 13 ] presented the state-of-the-art reviews and critically analyzed the use of TiO 2 nanotube coated on the various biomedical implant surfaces.…”

The aim of this study is to synthesize Titania nanotubes (TNTs) on the 3D-printed Ti-6Al-4V surface and investigate the loading of antibacterial vancomycin drug dose of 200 ppm for local drug treatment application for 24 h. The antibacterial drug release from synthesized nanotubes evaluated via the chemical surface measurement and the linear fitting of Korsmeyer–Peppas model was also assessed. The TNTs were synthesized on the Ti-6Al-4V surface through the anodization process at different anodization time. The TNTs morphology was characterized using field emission scanning electron microscope (FESEM). The wettability and the chemical composition of the Ti-6Al-4V surface and the TNTs were assessed using the contact angle meter, Fourier transform infrared spectrophotometer (FTIR) and the X-ray photoelectron spectroscopy (XPS). The vancomycin of 200 ppm release behavior under controlled atmosphere was measured by the high-performance liquid chromatography (HPLC) and hence, the position for retention time at 2.5 min was ascertained. The FESEM analysis confirmed the formation of nanostructured TNTs with vertically oriented, closely packed, smooth and unperforated walls. The maximum cumulative vancomycin release of 34.7% (69.5 ppm) was recorded at 24 h. The wetting angle of both Ti-6Al-4V implant and the TNTs were found below 90 degrees. This confirmed their excellent wettability.
