摘要
孔结构是影响金属多孔材料本征特性与使用效果的关键因素之一。孔结构分解为孔形状、孔弯曲与粗糙度、孔隙度、孔径、比表面积等几个方面,介绍了常用的表征技术和国内外测量仪器的发展状况及技术参数,并分析了表征技术中存在的问题。
Pore structure is one of critical factors for influencing intrinsic characteristic and application effect of metallic porous material. Pore structure is decomposed into pore shape, pore tortuosity and roughness, porosity, pore diameter and surface area. The usual characterization technology and development and technical parameters of internal measuring instruments were introduced, and the problems in characterization technology were analysed.
