“…While the process duration, potential, temperature and fluoride concentration are the main parameters that control the nanostructured titania layer thickness, diameter, and growth rate, different electrolyte features including pH, viscosity, conductivity, and organic additives can affect the process, leading to the formation of a nanotubular coating layer with undesired morphology or even to the non-formation of a nanostructured oxide layer [5,8,12]. In general, the most commonly used electrolytes for titanium anodization can be divided into two groups: organic, such as glycerol [26] and ethylene glycol [24]; and inorganic, such as HF [27], HF+H 3 PO 4 [17], NH 4 F+(NH 4 ) 2 SO 4 [28], H 2 SO 4 +HF [29].…”

A promising modification route to improve osseointegration of dental and medical titanium devices is a nanostructured titanium oxide coating layer in the form of self-ordered vertically aligned nanotubes (or nanotubular TiO 2 ). In this work, we report a detailed investigation of nanotubular TiO 2 coating layer on metallic Ti substrate prepared by anodic oxidation. The main goal was to determine an optimized and reproducible route to produce a nanotubular TiO 2 layer with homogenous morphology, narrow distribution and accurate control of the nanotube diameter. The influence of electrolyte temperature, anodizing time and applied voltage were studied, comparing three different electrolytes: 1.5 wt% HF, 0.5 wt% HF, and 0.5 wt% HF+1 mol l −1 H 3 PO 4 . Samples were analyzed by SEM, EDS, FIB, and XPS techniques. The most favorable result was achieved by using 0.5 wt% HF+1 mol l −1 H 3 PO 4 electrolyte, for anodizing time of about 90 min, temperature of 20°C, and anodizing potential from 1 to 25 V. Using these parameters, a uniform self-organized nanotubular TiO 2 layer was prepared with a fine control of the nanotube diameter value over a wide range (10 to 100 nm).

“…Titanium and its alloys are materials the mostly used for load-bearing implants, like endoprostheses of the hip joint. They possess a very good strength, high corrosion resistance, relatively low Young's modulus and above all they are highly biocompatible [1][2][3][4][5][6][7][8]. Among many titanium alloys used for implants, the most common is the Ti6Al4V alloy.…”

“…The anodic oxidation parameters such as time, voltage and electrolyte allow to control the effect the morphology of the resultant layer. The nanocrystalline structure of titanium oxide is composed of crystals of anatase possessing the same crystallographic structure as hydroxyapatite [1,10]. The bioactivation of the surface of titanium implants increases the potential biomechanical contact at the border implant-bone and affect the rate of adsorption of proteins [14].…”

The surface condition of an implant has a significant impact on response occurring at the implant-biosystem border. The knowledge of physical-chemical and biological processes allows for targeted modification of biomaterials to induce a specified response of a tissue. The present research was aimed at development of technology composing of obtaining the nanotube oxide layers on a porous titanium alloy Ti13Nb13Zr, followed by the deposition of phosphate coating. The porous substrate (porosity about 50%) was prepared by a selective laser melting of the Ti13Nb13Zr powder with the SLM Realizer 100 equipment. The nanotubular oxide layers were fabricated by electrochemical oxidation in H3PO4 + 0.3% HF mixture for 30 min. at a constant voltage of 20V. The calcium phosphate coatings were formed by the electrochemically assisted deposition (ECAD). The presence of nanotubular oxide layers with their internal diameters ranging from 30 to 100 nm was observed by SEM (JEOL JSM-7600F). The nanotubes have dimensions that facilitated the deposition of hydroxyapatite.

“…The growing interest in the use of titanium sheet products is due to the excellent properties of titanium, including high specific strength (strengthto-weight ratio) and good resistance to most corrosive environments. In addition, biocompatibility [16,27], allowing the correct functioning of titanium implants in living organisms, is well recognized in medicine as well as osteointegration with bone tissue, which creates good conditions for a durable and stable junction between an implant with the bone. The wide range of architectural capabilities associated with titanium anodic oxidation are of interest to civil engineering.…”

Due to the increase in the application of titanium components made of thin titanium sheets, in the work titanium panels made of 4 mm thick sheets are analysed. To increase the rigidity of the panels, some cross-shaped stiffeners were made. Such panels enable a reduction in weight while maintaining the existing strength of the drawn parts. Three kinds of commercially pure titanium are considered: Grade 1, 2 and 3. Numerical calculations were performed with PamStamp 2G based on the finite element method. The basic mechanical and technological properties of the analysed sheets, which are necessary for numerical modelling, were determined by static tensile testing. The friction coefficient was assumed based on the literature. On the basis of the performed numerical analyses, it was stated that the proper forming of panels with stiffeners depends not only on the drawability of the sheets but also on the technological parameters such as blank holder force and frictional conditions.
