摘要：
In this study electrochemical corrosion behavior of Zr(41.2)Ti(13.8)Ni(10)Cu(12.)5Be(22.5) bulk metallic glass (BMG) in various aqueous solutions (3.5% NaCl, 1 N HNO3, H2SO4 and HCl) in order to compare with 316L stainless steel were thoroughly investigated. Scanning electron microscopy (SEM) was used to evaluate the influence of corrosion on the surface topography in immersion specimens to examine where the corrosion pits initiated. Corrosion rate of Zr(41.2)Ti(13.8)Ni(10)Cu(12.)5Be(22.5) BMG in 3.5% NaCl solution was 0.6 mpy and its excellent corrosion resistance can be concluded. Polarization and SEM results also vouched a remarkable corrosion resistance of Zr(41.2)Ti(13.8)Ni(10)Cu(12.)5Be(22.5) BMG in 3.5% NaCI aqueous solution in comparison with 316L stainless steel.
