摘要: This work systematically reports the electrochemical properties and surface characteristics of Ni-based metallic glasses in boiling nitric acid solutions. The Ni-based glassy alloys demonstrate high corrosion resistance in boiling 6N HNO3 solutions with and without Cr6+ ions, which may be of great potential for nuclear fuel reprocessing applications. X-ray photoelectron spectroscopy analysis reveals that the high corrosion resistance of the alloys is due to the formation of the passive film composed exclusively of Nb5+ and Ta5+ cations …
