研究了Al85Ni9Ce6熔纺带在3.5 wt% NaCl溶液中室温浸泡1h后的表面化学性质和腐蚀行为。采用x射线光电子能谱（XPS）对Al85Ni9Ce6带的Al、Ce、Ni和o的化学状态进行了评价。合金在水中浸泡了48小时。结果表明，钝化膜中的氢氧化物对Al85Ni9Ce6合金的腐蚀行为起着重要作用。
The surface chemistry and corrosion behavior of Al85Ni9Ce6 melt-spun ribbons were studied after the first hours of immersion in 3.5-wt% NaCl solution at room temperature. X-ray photoelectron spectroscopy (XPS) was used to assess the chemical states of Al, Ce, Ni, and O. Electrochemical impedance spectroscopy was used to assess the corrosion resistance of the Al85Ni9Ce6 ribbons. The alloy remained immersed for up to 48 hours. The results showed that hydroxide species in the passive film play a central role in the corrosion behavior of the Al85Ni9Ce6 alloy.
