Abstract

The effects of dysprosium (Dy) on the adherence of Al₂O₃/NiAl interface were investigated by using first-principles theory calculations as well as experimental methods. The results showed that Dy could improve the adherence of the oxide/metal interface by two mechanisms: the first one was that Dy had a strong affinity for sulfur impurity in NiAl by the formation of Dy-S bonds, and thus can suppress the negative effects of sulfur; the second one was that Dy directly improved the Al₂O₃/NiAl interface adhesion by participating in bonding across the interface.
