electrochemical measurements and immersion test in Hank’s simulated body fluid.The results reveal that with the increase of strontium addition

the second phase（SrZn13）in the microstructure of zinc alloy is gradually increased with the increase of the size

resulting in the increase of the hardness gradually

while the corrosion resistance is deteriorated.The micro-hardness of Zn-xSr（x=0
