中文摘要	in this paper we present a new method for measuring diffusion coefficients in liquid metals under convection-less conditions with solid/liquid-liquid/solid trilayer. the advantage of this kind of trilayer is that effects from gravity-induced convection and marangoni-convection can be omitted, so that the diffusion coefficient is determined more accurately. the ta/zn-sn/si trilayer were prepared with a multi-target ion-beam sputtering deposition technique and annealed in an electric furnace under an argon atmosphere. the interdiffusion of liquid zinc and tin at 500 degrees degree c was investigated. the diffusion concentration profiles were determined by energy dispersive spectroscopy. the interdiffusion coefficients range from 1.0x10(-6)cm(2)/s to 2.8x10(-6)cm(2)/s, which is less than previous values measured by capillary reservoir technique under 1g-environment where various convection exist. the precise interdiffusion coefficients of liquid zinc and tin result from the removing of disturbances of various kinds of convection.
