Paper presents study on the hydrothermal treatment for hydroxyapatite layer formation on the different biodegradable Mg-substrates.The evaluation of corrosion resistance in Ringer’s solution and contact angle measurements in glycerol Stem Wine Glass were performed.Alloys and composites substrates obtained by mechanical alloying and powder metallurgy route are characterized by submicron range microstructure, which is responsible for further surface processing characteristic.Hydrothermal treatment in Ca-EDTA Misc robotics mecha (ethylenediaminetetraacetic acid calcium disodium salt) led to formation of hydroxyapatite layers, which improves both the corrosion resistance and surface wetting properties compared to microcrystalline magnesium.
