N2 - In this research, the corrosion behavior and mechanical properties of the Mg-Zn-Ca amorphous alloys, as well as the effects of Ag addition were investigated. The results revealed that the as-cast Mg65Zn 30Ca5 amorphous alloy exhibited the high fracture strength over 720 MPa, which was further enhanced by 1% Ag addition. The polarization resistances in Hanks' solution of high purity Mg, Mg65Zn 30Ca5, Mg65Zn30Ca4Ag 1 and Mg63Zn30Ca4Ag3 amorphous alloys were 5710, 5640, 8542 and 4125 Ohms/cm2, respectively. The minor addition of 1% Ag and homogeneous structure are responsible for improved strength and polarization resistance. With more Ag addition, both the strength and corrosion resistance were decreased due to the deceasing of the glass forming ability and galvanic corrosion.
