Abstract Magnesium alloy has excellent physical and mechanical properties is expected to become a new generation of medical degradable materials. In this paper, the blood compatibility analysis Graphene Oxide(GO) / Hydroxyapatite(HA)-AZ91D was carried out improve magnesium AZ91D used as control group GO/HA-AZ91D experimental group. The two samples were studied in vitro by hemolysis rate test, c...
