Abstract:
1. A method for forming a composite using electrodeposition, the method comprising: providing a bath including at least two electrodepositable components; connecting a porous preform including accessible interior void structures to a first electrode; inserting the porous preform into the bath; inserting a second electrode into the bath; and applying time varying voltage or current to the first electrode where the time varying voltage or current oscillates at least for two cycles to deposit a compositionally modulated material within the accessible interior void structure of the porous preform; wherein said porous preform is a graded element; and wherein said graded element comprises a particle bed having layers of different sized particles or a foam having layers consisting of different porosities.
