“…TiO 2 nanotubes were aligned vertically and densely packed. The TiO 2 nanotube layers were previously obtained on a titanium alloy using electrolytes with orthophosphoric acid and hydrofluoric acid [34,35]. Nanotubular titanium dioxide layers designed to ensure better adhesion between the substrate and coatings and for improved corrosion resistance of titanium alloy have also been investigated in the past [36,37].…”

The surface treatment of titanium implants has been applied mainly to increase surface bioactivity and, more recently, to introduce antibacterial properties. To this end, composite coatings have been investigated, particularly those based on hydroxyapatite. The present research was aimed at the development of another coating type, chitosan–nanosilver, deposited on a Ti13Zr13Nb alloy. The research comprised characterization of the coating’s microstructure and morphology, time-dependent nanosilver dissolution in simulated body fluid, and investigation of the nanomechanical properties of surface coatings composed of chitosan and nanosilver, with or without a surface-active substance, deposited at different voltages for 1 min on a nanotubular TiO2 layer. The microstructure, morphology, topography, and phase composition were examined, and the silver dissolution rate in simulated body fluid, nanoscale mechanical properties, and water contact angle were measured. The voltage value significantly influenced surface roughness. All specimens possessed high biocompatibility. The highest and best adhesion of the coatings was observed in the absence of a surface-active substance. Silver dissolution caused the appearance of silver ions in solution at levels effective against bacteria and below the upper safe limit value.

“…There are some reports on possible adverse e effects of both alloying elements of the Ti6Al4V: vanadium may provoke cytological responses and neurogenic disorders, and aluminum softens bone, do damage to nerve cells and disturbance of the function of enzymes [7][8][9][10]. The titanium alloy Ti13Zr13Nb possesses no harmful elements (aluminum and vanadium), is characterized by relatively low Young modulus (~ 80 GPa ) [8] compared to Ti6Al4V (~110 GPa) [11] and is more mechanically compatible with the bone (15)(16)(17)(18)(19)(20) [12,13].…”

The aim of this research was to study the properties of nanohydroxyapatite (nanoHAp) and nanohydroxyapatite, doped with nanosilver (nanoHAp/nanoAg), coatings obtained by an electrophoretic deposition process. The suspensions was prepared by dispersing 0.1 g of HAp nanopowder for nanoHAp coatings and 0.1 g of nanoHAp and 0.025 g nanoAg for nanoHAp/nanoAg coatings. The deposition was carried out for 1 min at 50 V voltage followed by drying at room temperature for 24 h and heating at 800°C for 1 h in vacuum. The thickness of the nanoHAp and nanoHAp/nanoAg coatings was found as of about 5 µm. The corrosion behavior tests made by potentiodynamic methods brought out slightly higher values of corrosion current for nanoHAp coatings and nanoHAp/nanoAg coatings as compared to the reference Ti13Zr13Nb specimen. The nanohardness of the nanoHAp coatings achieved 0.020 ± 0.004 GPa and of the nanoHAp/nanoAg coatings 0.026 ± 0.012 GPa. Nanoscratch test of the nanoHAp and nanoHAp/nanoAg coatings revealed an increased Critical Friction (mN) in the presence of nanosilver particles. The wettability angles decreased for nanoHAp/nanoAg coatings comparing to pure nanoHAp coatings on titanium alloy.

“…El vanadio se vio sustituido por niobio para estabilizar la fase β en valores cercanos a la temperatura ambiente. Mediante esta modificación de la composición química de la aleación se consigue mejorar la resistencia a la corrosión y biocompatibilidad de las aleaciones α+β (Iijima et al, 2003;Chlebus et al, 2011;Nguyen et al, 2013;Ossowska et al, 2014).…”

RESUMEN:El envejecimiento de la población junto con el incremento de la esperanza de vida, obligan al desarrollo de prótesis que presenten un periodo de vida útil cada vez mayor. El éxito clínico de los implantes está basado en la consecución de la osteointegración. Por lo tanto, las prótesis metálicas necesitan disponer de una compatibilidad mecánica con el hueso que sustituyen, que se consigue mediante una combinación de bajo módulo elástico, alta resistencia a la rotura y a fatiga. La mejora, a corto y largo plazo, de la osteointegración es función de múltiples factores, de entre los cuales son de gran importancia su diseño macroscópico y dimensional, el material y la topografía superficial del implante. Este artículo se centra en resumir las ventajas que presentan el titanio y sus aleaciones para ser empleadas como biomateriales, y la evolución que han sufrido estas, en las últimas décadas, para mejorar su biocompatibilidad. En consecuencia, se ha recapitulado la evolución que han sufrido los implantes, resumiéndose a través de tres generaciones. En los últimos años se ha incrementado el interés en los tratamientos superficiales de las prótesis metálicas, con el objetivo de alcanzar una integración del tejido óseo duradera y en el menor tiempo posible. En este artículo se exponen varios tratamientos superficiales utilizados actualmente para modificar la rugosidad o para obtener recubrimientos superficiales; cabe destacar la oxidación electroquímica con tratamiento térmico, para modificar la estructura cristalina de los óxidos de titanio. Tras la revisión bibliográfica llevada a cabo para la redacción de este artículo, las aleaciones β de titanio, con una superficie de nanotubos obtenida mediante oxidación electroquímica y una etapa posterior de tratamiento térmico para obtener una estructura cristalina, son la opción de futuro para mejorar la biocompatibilidad a largo plazo de las prótesis de titanio. ABSTRACT: Development of titanium alloys and surface treatments to increase the implants lifetime. The population aging together with increase of life expectancy forces the development of new prosthesis which may present a higher useful life. The clinical success of implants is based on the osseointegration achievement. Therefore, metal implants must have a mechanical compatibility with the substituted bone, which is achieved through a combination of low elastic modulus, high flexural and fatigue strength. The improvement, in the short and long term, of the osseointegration depends on several factors, where the macroscopic design and dimensional, material and implant surface topography are of great importance. This article is focused on summarizing the advantages that present the titanium and its alloys to be used as biomaterials, and the development that they
