Resumen
The synthesis and study of biomaterials possessing biomechanical and biocompatibility properties is a subject of continuous research by the scientifi c community. Compounds such as hydroxyapatite (HA) and brushite, which have interesting properties and are biocompatible, are being used as a barrier layer between materials such as 316L steel and biological media, thus reducing the iron ion fl ux from the steel to the Biological fl uids. Although recent studies have presented advances regarding the adhesion of these materials to diff erent metals, there are still open challenges to improve the adhesion of these materials to the desired metal. In this work, we have implemented coatings composed of brushite and titanium dioxide (TiO2) bilayers. Following are the protocols followed for synthesis of brushite, titanium dioxide and bilayer coatings on 316 L steel, as well as the structural characterization by infra-red spectrometry (FTIR), X-ray diff raction (XRD), electron microscopy of Scanning (SEM) and dispersive energy spectroscopy (EDS) of the coatings obtained.
