“…Since then, researchers have actively performed many studies on the applications of sodium titanate thin films in implants Nishiguchi et al, 1999;Jonášová et al, 2003;Muramatsu et al, 2003;Wang et al, 2007;Wang et al, 2008). Similar studies have also been performed on calcium titanate thin films (Hanawa et al, 1997;Hamada et al, 2002;Nakagawa et al, 2005;Kon et al, 2007;Ohtsu et al, 2008), titanium dioxide thin films (Ohtsuki et al, 1997;Wang et al, 2001;Wang et al, 2003;Byon et al, 2007), and a nanohydroxyapatite thin film (Xiong et al, 2010), and the excellent biocompatibilities of these films have been reported. Therefore, titanium compound thin films show tremendous promise for use as implant materials.…”

“…On a Ti-Nb alloy substrate, 1) when T h was 200 o C, a dense nanoHA layer formed on the substrate at 5h ≤ t h ≤ 12 h; and 2) TiO 2 and Nb 2 O 5 formed on the surface of the substrate during the hydrothermal treatment, which, then, transformed into Ti(OH) 4 and Nb(OH) 5 , respectively [53].…”

“…First, a buffer solution was prepared by dissolving HEPES buffering agent in NaO aqueous solution, followed by dissolution of K 2 HPO 4 and CaCl 2 , and adjustment of pH to 7.4. Second, the bioalloy specimen was placed in a beaker, the buffer solution was poured in the beaker, and the solution was hydrothermally treated at a temperature (T h ) of 80-200 o C for a time (t h ) of 5-12 h [53]. In the third step, the specimen was ultrasonically washed in distilled water for 5 min and, then, dried in air at 50 o C for 24 h [53].…”

Abstract. Several shortcomings of the alloys that are used to fabricate a number of currentgeneration biomedical implants, such as Ti-6Al-4V alloy for the femoral stem of a total hip replacement and AZ3 Mg alloy for the scaffold of a fully bioabsorbable coronary artery stent, are well-known. Examples of these shortcomings are limited bioactivity/osseointegration (in the case of Ti-based alloys) and high corrosion rate (in the case of Mg-based alloys). It is now recognized that a nanostructured hydroxyapatite (nanoHA) coating on the substrate of a bioalloy can increase bioactivity and reduce corrosion of the substrate. A large number of nanoHA deposition methods and a variety of characterization techniques/methods have been used to obtain an assortment of properties of the coating, the coated specimens, and the coating-substrate interface. Examples of these deposition methods are electrophoretic deposition and radiofrequency magnetron sputtering and some of the most frequently used characterization techniques/methods are x-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, atomic force microscopy, immersion tests in a biosimulating solution at 37 o C, and culturing in cells extracted from humans. Among the properties obtained are the morphology, thickness, size of the nanoHA; degree of crystallinity of the coating; and the adhesive strength and corrosion rate in an aqueous biosimulating solution at 37 o C. The present work is a comprehensive review of the very large body of literature in this field, with the focal topics being essential steps in a deposition method, discussion of the influence of deposition method variables on myriad coating properties (for a given deposition method), and identification of the shortcomings of the literature, and, hence, outlines of ten suggested directions for future research.
