In this research, porous magnesium-zinc scaffolds were prepared by powder metallurgical process and nano hydroxyapatite (HAP) coating on the Mg-3Zn (wt.%) scaffold was prepared by pulseelectrodeposition and alkali treatment processes to improve the corrosion resistance of the scaffold. Theresults 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-foldin comparison to the scaffold modified by nano hydroxyapatite coating
