“…9, below). The sample obtained by DC magnetron sputtering shows the planes characteristic of TiO: (0 3 1) and (-2 1 1) at 37.24°and 37.43°, respectively [20], while the sample obtained by DC magnetron sputtering and additionally thermally treated shows the planes characteristic of anatase: (1 0 1), (0 0 4) and (1 1 2) at 25.27°, 37.72°and 38.58° [21,22], respectively, as well as planes characteristic of rutile: (1 0 1) and (2 0 0) at 36.08°and 39.15° [23]. Formation of the anatase and rutile phases in the second sample indicates that the recrystallization process took place in the system during the additional thermal treatment.…”

Thin films of titanium oxides, titanium oxynitrides and titanium nitrides were deposited on glass substrates by the methods of direct current (DC) and pulsed magnetron sputtering and cathodic arc evaporation. Phase analysis of the deposited films by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) showed the presence of phases with various Ti oxidative states, which indicated a high concentration of oxygen vacancies. The films morphology was investigated by scanning electron microscopy (SEM). Investigations of the films wettability, either with water or ethylene glycol, showed that it depends directly on the concentration of oxygen vacancies. The wettability mechanism was particularly discussed.

Bioceramic coatings on metallic implants provide a wear-resistant and biocompatible layer, that own ability to develop bone-like apatite in physiological environments to ensure bonding with hard tissues. These bioceramics primarily belong to Calcium Phosphates (CaPs), bioactive glasses, and glass-ceramics. Several techniques are used to deposit these coatings such as; electrophoretic deposition (EPD), plasma spray (PS), and Radio frequency magnetron sputtering (RFMS). Most of these techniques require a high-temperature operation or sintering treatment. This causes either thermal decomposition of bioceramic or results in delamination and cracking of the bioceramic coating due to differences in thermal expansion behavior of metals and bioceramics. RFMS is primarily carried out either at room temperature. However, annealing is performed or substrate is heated at various temperatures ∼400–1,200°C for 2 or 4 h under dry argon (very low temperature compared to other techniques) to ensure crystallization of bioceramics and improve coating adhesion. Chemical composition stability and excellent surface finish are the premium features of RFMS, due to less heat involvement. Moreover, RFMS has the unique ability to develop one-unit/ multilayered composite coatings and the flexibility of in-situ reactions to yield oxides and nitrides. Single or multiple targets can be employed with the insertion of Oxygen and Nitrogen to yield versatile coatings. Due to this attractive set of features RFMS has a strong potential in the field of bioceramic coatings. In recent years, several multifunctional bioceramic coatings have been deposited on metallic substrates using RFMS for biomedical applications. This review focuses on the recent efforts made in order to deposit multifunctional bioceramic RFMS coatings with surface characteristics necessary for biomedical applications and highlights future directions for the improved biological performance of RFMS bioceramic coatings.

“…of the formed oxidation layer that effectively promoted the chemical affinity between the underlying titanium and the upper ceramic layer. According to the literature [39,40], titanium oxide can be used as a bond layer for improving the bond strength of coatings to metallic substrate. Nevertheless, when annealed at higher temperature such as 900 °C, the excessive thickness (e.g., 4.75 μm) of the oxidation layer near the titanium substrate may result in poor adhesion, in turn, detrimental to the bonding, although possessing a higher crystallinity of rutile phase.…”
