Biocompatible Hybrid Surface Layers on Porous Magnesium Structures Fabricated by Spark Sintering

In this study, 3D Mg scaffolds were obtained by the spark plasma sintering (SPS), and a calcium phosphate coating was then obtained on the samples by the plasma electrolytic oxidation. A hybrid coating with vancomycin, zoledronic acid and menaquinone MK-7 was formed additionally to improve biocompatibility. The mechanical properties of the formed specimens were studied. According to XRF, SEM, EDS and OSP studies obtained scaffolds have developed morphology and contain hydroxyapatite as well as bioactive substances. Formation of coatings improves samples wettability as well as wear resistance. This makes them promising for use as a new generation of implantation materials. The results are important for the development of personalized implants with improved functional characteristics.
