The project is focused on the study of the possibility of preparation and characterization of biodegradable material on the base of Mg powders with controlled degradation rate. Magnesium-based materials made from ingots have poor mechanical properties and rapidly in the corrosive conditions. As an alternative is to produce the material from Mg powders which can significantly enhance the properties. Powder metallurgy (PM) is a modern method of processing where specific mechanical properties are achieved due to high purity, material structure and controlled porosity. The degradation rate being controlled by surface treatment of powders prior to compaction, or by admixture of a suitable biocompatible material with the healing effect. The material will be prepared by the direct extrusion method, while examination of the effect of the produced native oxides on the extrusion parameters will be necessary. Mechanical and corrosion properties will be examined and in vitro bioassays will be performed.
