The Effects of Hydroxyapatite on the Corrosion Behaviour of AZ Series Mg Alloys

Metallic biomaterials are widely used in the orthopedic and dental applications owing to their advanced biocompatibility sophisticated mechanical properties. Many studies carried out develop new alloys with high specific strength, corrosion resistance as an alternative present metallic biomaterials. Mg potential a biomaterial, especially because they have low density biocompatibility. However, properties of need be improved. In this study, surfaces AZ31, AZ61 AZ91 alloys, which promising biomaterials, were coated hydroxyapatite biocompatibility, effects bioceramics coatings on comprehensively investigated. Crack-free porous surface morphologies obtained all bioceramic presence was supported by EDS analysis. As result tests performed SBF, it determined that alloy had highest among uncoated samples. The also improved samples, alloy.
