Abstract
Principles of the preparation of nickel foam by electrolyte jet electrodeposition were introduced, Nickel foam samples
with different porosity were fabricated. Effect of different porosity on microhardness and uniaxial tensile properties of
nickel foam was discussed. The results show that the microhardness of nickel foam is 320~400 HV, lower than entitative
metal clearly. The lower the porosity of nickel foam, the higher the microhardness is. During the process of uniaxial
tensile, nickel foam is characterized by three distinct regions, e.g. elastic deforming region, plastic plateau region and
densification region. The higher the porosity of nickel foam, the lower the plastic plateau and the poorer the strength of
nickel foam, accordingl
