Abstract To improve the corrosion resistance of Zr51.3Al10Ni6Cu31.8Ag0.1Y0.8 metallic glass in acid chloride solution, Ti was added into the alloy. XRD results show these Ti-added alloys with diameters of 3 mm are all metallic glasses. Weight loss and electrochemical method were introduced to characterize their corrosion resistance. Results show that the corrosion resistance of metallic glass is significantly improved with Ti addition. XPS study demonstrates that Zr dioxides dominate in passive film during corrosion when Ti content is low. High-content Ti addition can lead to an evident accumulation of Ti dioxides, this accumulation results in a thicker, Ti-enriched protective passive film.
