摘要：

Mg alloys are outstanding candidates for the use in automotive, aerospace and electronic industries because of their low density and excellent strength to weight ratio. In particular, the extruded Mg sintered alloy produced by SWAP has more excellent mechanical property than other Mg materials. In this study, their corrosion behavior has been investigated by the polarization test and electrochemical impedance spectroscopy test for their practical use. AZ31 sintered alloy sample produced by SWAP showed good corrosion resistance because of its homogeneous structure.
