Abstract :
In this paper we used a gel based on calcium acetate / phosphoric acid in which the molar ratio Ca: P was 1.69 in order to obtain a hydroxyapatite layer on a metallic substrate of an implantable titanium alloy. Thin layers have good homogeneity and adhesion to the substrate and defects in the coating were investigated by scanning electron microscopy (SEM) and energy dispersive analysis of X-rays (EDAX).
