提出了一种根据泡沫金属的孔率和孔径这两个基本参量计算其比表面积的方法. 利用泡沫金属比表面积与孔率和孔径的对应数理关系, 结合有关实验数据,成功地计算出了电沉积法和高压渗流铸造法制备的泡沫金属的比表面积.
By means of two elementary parameters, a method has been put forward to calculate the specific surface area from porosity and pore diameter for metal foams. Using the relevant mathematicalphysical relationship between the specific surface area and the elementary parameters of porosity and pore diameter, the specific surface areas of two classes of metal foams, which were respectively prepared by different technologies of electrical deposition and high pressure permeating casting, are successfullycalculated out.
