Abstract

A composite coating consisting of Mg-Fe LDH intercalated with 8-hydroxyquinoline (8HQ) and modified with citric acid (CA) layer is constructed on Mg alloy WE43 via combination of electrodeposition, hydrothermal and anion-exchange. In view of CA and their small “island-shaped” surface morphology, the CA coating could provide MgFe LDH film with physical and chemical shielding. The intercalation of 8HQ into the MgFe LDH/0.05CA saw further enhancement in corrosion resistance as 8HQ hinders anodic and cathodic dissolution reaction. Furthermore, the MgFe-8HQ LDH/0.05CA coating presented a possible self-healing based on the 7-day EIS study, establishing as a potential coating for biomedical implant applications.
