Microstructure of Hydroxyapatite/Collagen Coating on AZ31 Magnesium Alloy by a Solution Treatment

HA and HA/Col were prepared by a solution treatment on AZ31 magnesium alloy. The microstructure and composition of coatings were studied by SEM, XRD. In vitro study was performed by immersion the sample In Hank’s solution for 7 days. The H2 evolution of the HA/col coating was as low as 0.24 ml/cm2 which can insignificant increase the corrosion resistance of AZ31.
