of corrosion reaction falls down. As a result, the corrosion rate drops and corrosion becomes slower and slower. Zn is the major hardening element in Mg-Zn-Zr alloy with the reinforcing phase MgZn that is electrochemically negative. Zr can remarkably improve the corrosion resistance of the Mg-Zn alloy due to the high potential needed to release hydrogen. The addition of Y increases the solubility......
