ELECTROPHORETIC DEPOSITION OF MATERIALS

The electrophoretic deposition of materials is reviewed. Numerous applications of electrophoretic deposition are described, including production of coatings, free-standing objects, and laminated or graded materials, infiltration of porous materials, and fabrication of woven fiber preforms. The preparation of electrophoretic suspensions is discussed as are a number of mechanisms of deposition that have been proposed elsewhere. In discussing the kinetics of the process, primary attention is given to the relation between the evolution of the current and the electric field strength.
