Interfacial reactions between liquid Zn and Zr substrate were investigated in this paper using Zn(liquid)/Zr(solid) reaction couples. The results showed that when the reaction couples reacted at 450℃and 530℃, the reaction layers consisted of Zn3Zr, Zn39Zr5 and Zn22Zr in sequence. When the reaction couples reacted at 580℃, only Zn22Zr and Zn39Zr5 were formed at the interface. The thickness of the reaction layers increased with the growth of reaction temperature and time. The growth kinetics of the interfacial reaction layer satisfied a parabolic relationship. The thickness of the Zn22Zr reaction layer increases quickly at the initial stage and keeps invariant with the growth of reaction temperature and time when the reaction reaches equilibrium. Shrinking of the reaction layers at the corners is observed in the Zn(l)/Zr(s) reaction couples, but it does not exhibit a typical cruciform pattern.
