The interaction between Zn (solid and liquid state) and the Ni3Si substrate at 390-480℃ was investigated employing a combination of X-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy.The interaction result in the formation of a periodic layered structure,which consists of alternating T and γlayers and with a typical periodic layer pair thickness of 1-3μm.The reaction zone was found to grow by a parabolic law,the growth process is controlled by Zn diffusion to Ni3Si substrate and Ni diffusion to the T/γ interface.A diffusion path model describing the formation of the layered structure in the Zn/Ni3Si system is firstly presented.
