The patent application relates to a possibility to reduce the degradation rate of Mg alloys used for the maxillofacial surgery by coatings with thin films-based hydroxyapatite prepared by RF magnetron sputtering. The coatings exhibit a thickness ranged from 250 nm to 300 nm nm, being deposited up to 400⁰ C. These coatings resist to corrosive attack of SBF, DMEM and PBS at 37⁰C, having a high protective efficient in these corrosive media (min 82%).
