Abstract
The magnesium matrix double interpenetrating composites reinforced by nickel foam were fabricated by pressureless infiltration technology. Then the morphology of the nickel reinforcement and the microstructures of composites were characterized by SEM. The results show that not only is the nickel foam reinforcement reticular in three dimensions, but also the struts of foam keep the network structure, which ensures that the Ni foam/Mg composites are double interpenetrating. The interface bonding of composites between magnesium matrix and nickel foam reinforcement is good, without reaction around the interface, which is the indispensable condition that advanced composites should possess. Magnesium matrix distributes in the windows of nickel foam, the triangle center holes and microhole of nickel struts, and the composites have double interpenetrating structure, which makes the composites have unique properties.
