Growth of phosphate coating on titanium substrate by hydrothermal process

Titanium surface characteristics determine the degree of success of permanent implants. The topography, morphology of the surface in micro and nano scales, the impurities present and other characteristics are a main concern, and therefore a multi‐technique approach is required in order to evaluate modification process effects on the surface. Surface modification of titanium in the nanometrical range was performed by means of anodisation in phosphoric with the aim of improving both the biocompatibility and the corrosion resistance in the biological media. Biocompatible characteristics of the modified titanium surface, as the presence of anatase in the oxide film and the incorporation of phosphate to the surface, were determined. Moreover, the electronic properties of the surface oxide presented a carrier number adequate for biomedical applications. The increase in the film thickness from 3 to 42 nm was estimated from EIS results when anodising potentials from 0 to 30 V were applied, whereas a bi‐layer structure of the protective oxides formed was determined.

Calciumhydroxyapatite thin films have been prepared by ultrasonic spray pyrolysis deposition on titanium substrate. The surface morphologies of the films formed at different deposition times were analysed by using SEM. The mechanism of the films formation was investigated in relation to the observed film morphology during the first stages of its formation, as well as to its consolidation to the final form. The chemical homogeneity of the synthesized films was determined by using EDS analysis, whereas the phase composition was determined by using XRD measurements and IR spectroscopy. The roughnesses and the thicknesses of the films were analysed by using surface profiler method. The continuous morphology films are obtained only for samples deposited more than 1.5 h.
