i-Cu非晶合金纳米多孔的制备

Nano-porous metal materials have many excellent properties and potential applications in many fields，which led to the research boom of the nano-porous metals by domestic and foreign research scholars. In this paper, we study the procedure of nano-porous structure made on Ti-Cu metallic glass by dealloying. We obtain the optimum process parameters by controlling the solution concentration, reaction temperature, reaction time, load voltage and sample composition of the amorphous alloys in the procedure. By using these optimum process parameters, we have prepared the nano-porous metal, on which the distribution of pores are uniform, the average pore size is about 50nm and the average pore wall thickness is about 100nm.
