Abstract

Metal foams are a relatively new class of materials. They provide a high energy absorption ability, large surface to volume ratio, and a high stiffness to weight ratio because of the existence of porosity in their structure. One of the most applicable metal foams is nickel foam used as catalysts, filters, and silencers in different industries. In this work, Ni foam has been prepared by electrodeposition technique on a polyurethane sponge substrate. The produced foams were sintered at 600℃ and 1000℃ in the neutral atmosphere to eliminate organic substrate and increase their ductility. EDX analysis showed that carbon atoms have diffused into Ni deposition during sintering at 600 ℃ , and also the samples sintered at 1000 ℃ have oxidized. The pressure tests indicated that the samples were ductile after the sintering process. By increasing ductility, plateau strength will reduce from 4. 79 MPa to 3. 6 MPa and 1. 65 MPa for the samples sintered at 600℃ and 1000℃ , respectively. Obtained results showed that heat treatments didn’ t have any effects on the densification strain, but energy absorption reduced from 1. 51 MJ/cm2 to 1. 21 MJ/cm2 and 0. 55 MJ/cm2 for the sintered samples at 600℃ and 1000℃ , respectively.
