In order to enhance their stiffness, strength and energy absorption capability open-cell aluminum foams have been coated with nickel by electrodeposition. The coating thickness distribution is very important for the properties of the coated foams. A method to assess the coating thickness distribution by scanning the magnetic flux density distribution has been evaluated. The mechanical behavior has been investigated by quasi-static compression tests. The energy absorption capability increases linearly with the coating thickness, both for the absolute values and per foam thickness, but per density or mass the energy absorption capability reaches a saturation level. So there is an optimum in coating thickness. A decrease in pore size from 10 to 30 ppi more than doubles the energy absorption capability per foam thickness of coated foams.
