“…TiO 2 can promote the formation of bone-like apatite or calcium phosphate on its surface when soaked in SBF solution which makes it suitable for bone reconstruction and replacement [201]. Moreover, it was found that the formation of TiO 2 coating by anodization on the surface of Ti substrates was an effective method to reduce the temperature rise of the implant during microwave diathermy treatment that would provide a potential rehabilitation solution to internal fixation of bone fracture [202]. Similar to TiO 2 , tantalum oxide (Ta 2 O 5 ) could facilitate the formation of bone-like apatite and stimulate the rapid attachment of bone and soft tissue [189].…”

To fix the bone in orthopedics, it is almost always necessary to use implants. Metals provide the needed physical and mechanical properties for load-bearing applications. Although widely used as biomedical materials for the replacement of hard tissue, metallic implants still confront challenges, among which the foremost is their low biocompatibility. Some of them also suffer from excessive wear, low corrosion resistance, infections and shielding stress. To address these issues, various coatings have been applied to enhance their in vitro and in vivo performance. When merged with the beneficial properties of various bio-ceramic or polymer coatings remarkable bioactive, osteogenic, antibacterial, or biodegradable composite implants can be created. In this review, bioactive and high-performance coatings for metallic bone implants are systematically reviewed and their biocompatibility is discussed. Updates in coating materials and formulations for metallic implants, as well as their production routes, have been provided. The ways of improving the bioactive coating performance by incorporating bioactive moieties such as growth factors, osteogenic factors, immunomodulatory factors, antibiotics, or other drugs that are locally released in a controlled manner have also been addressed.

“…Current work on improving the quality of implants used in the treatment of skeletal disorders focusses its attention primarily on improving the physicochemical properties of their surfaces [1][2][3]. Good corrosion resistance, confirmed by numerous studies, for titanium alloys is provided by the ability to self-assimilate.…”

Surface modification techniques play an important role in adjusting the physicochemical properties of titanium and its alloys. To reduce the penetration of alloying element ions into the body, various types of oxide coatings are used to protect it from the corrosive environment. Another important issue related to the surface layer requirement is ensuring an appropriate set of mechanical properties. Accordingly, in this study, the mechanical and electrochemical properties of the silicon dioxide layers formed by the deposition of nano physical vapor deposition on the surface of titanium and titanium 13‐niobium 13‐zirconium alloy samples were investigated. To evaluate the mechanical properties of the layers produced by this method, hardness tests were carried out, as well as tests on the adhesion of these layers to the metal substrate. On the other hand, electrochemical properties were studied using potentiodynamic measurements to assess the resistance to pitting corrosion, followed by impedance measurements to interpret the processes and phenomena occurring at the silicon dioxide layer/electrolyte interface. The data obtained showed different mechanical and electrochemical properties of the silicon dioxide layers generated with varying process parameters.

“…Additionally, the layer consists of a chemically stable TiO 2 layer and contains less than ~5 at% Ni inclusions. This makes the surface hydrophilic 4 and improves its corrosion resistance 5–7 . In recent years, NiTi alloys have been used as implanting devices, such as cardiovascular stents, in cardiology 8–10 .…”

Pulsed anodization of superelastic NiTi alloy in nitric acid electrolyte is a novel surface modification process that enables the formation of an almost Ni-free TiO 2 layer on their surface. The core technology is the modulation of voltage-unapplied state that is necessary for the chemical reaction with an electrolyte. Here, the effect of the adjustment of the voltage-unapplied state on the layer characteristics was investigated. Prolongation of the voltage-unapplied state led to the formation of a thicker
