The Effect of Sintering Condition on Microstructural and Mechanical Properties of Porous Nickel

Abstract:

The relationship between temperature of sintering in neutral atmosphere and compression strength has been investigated for nickel foams produced by electrodeposition on an organic foam. The as-plated nickel foams are sintered at 600and 1000 in order to eliminate polyurethane and enhance ductility. The results show that the compression strength is significantly influenced by sintering temperature. The most ductile sample is gained by sintering at 600. In addition, samples sintered at this temperature have the higher energy absorbing capability. EDX analyses show that oxygen element raised from oxidation in high temperature presents in specimen sintered at 1000. Hollow struts are obvious in SEM image of treated foams.
