Abstract
Magnesium has been recently recognized as a biodegradation metal for bone substitute application. In the present work, porous magnesium-zinc scaffolds were prepared by powder metallurgical process and nano hydroxyapatite (HAP) coating on the Mg-3Zn (wt.%) scaffold was prepared by pulse electrodeposition and alkali treatment processes to improve the corrosion resistance of scaffold. The results indicated the as-deposited coating consists of HAP, DCPD and OCP with needle-like and plate-like structures and the post-treated coating was composed of needle-like particles of nano HAP that developed almost perpendicularly to the substrate. Electrochemical tests showed that the corrosion potential of scaffold significantly increased from –1.475 to –1.365 V and the corrosion current density reduced 1.5-fold in comparison to the scaffold modified by nano hydroxyapatite coating.
