Characterization Technology of Pore Structure of Metallic Porous Materials

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.
