Fabrication of Tailored Powder Structures by Electrophoretic Deposition and Sintering

Article Preview

To enable sintering net-shape capabilities, a novel procedure for the fabrication of net-shape functionally graded composites by electrophoretic deposition and sintering are developed. The initial shape of the green specimen produced by electrophoretic deposition is designed in such a way so that the required final shape is achieved after sintering-imposed distortions. The shaped components can be metals, ceramics, polymers, and their combination as long as the material is in the form of powders. Through adjustment of an externally applied electric field and the shielding of electrical filed, the particles in the slurry are selectively deposited onto the porous mold which defines the desired geometry. By changing the slurries’ composition, the deposited component’s composition can be precisely tailored.
