英文摘要	Heretofore, recognitions of the systematic effects of scandium addition on corrosion behavior of biodegradable magnesium alloys are not yet clear. In the present study, a series of Mg-1.5Zn-0.6Zr-xSc (ZK21-xSc, x = 0, 0.2, 0.5, 1.0 wt.%) alloys were casted and investigated with respect to the immersion and electrochemical degradation behavior. The hydrogen evolution, pH monitoring, ion release and mass loss results demonstrated that ZK21-0.2Sc alloy exhibited the lowest corrosion rate. The surface morphology analyses displayed that an obvious uniform corrosion occurred in ZK21-xSc alloys with Sc content below 0.5, while localized corrosion occurred in ZK21-1.0Sc alloy. Corrosion potentials of ZK21-xSc alloys shifted toward more positive with the increasing Sc content. But ZK21-0.2Sc alloy exhibited the lowest corrosion current density and the largest corrosion film resistance. Compared with other developed Mg alloys, the ZK21-0.2Sc alloy demonstrated a superior degradation behavior.
