The demand for metal matrix composites MMC is reaching a new height in the material community in view of their superior strength at elevated temperatures. Several methods are employed in producing these composites in which high strength inert particles, fibers, or filaments are incorporated in the matrix of a conventional metal. A critical problem in producing metal matrix composites is the handling and damaging of candidate brittle high strength fibers due to high process temperatures and pressures. A process for producing composites, which does not require high temperatures or pressures, is electrodeposition in aqueous solutions which offers a number of other benefits. Electrocomposites are reinforced electrodeposits or electroforms with high strength inert particles, fibers, or continuous filaments. From a review of the literature, an updated evaluation of electrocomposites is given, followed by a review of their strengthening mechanisms and the proposed theories of particle encapsulation. The results and properties of electro composites previously reported are also reviewed and the future role that platers have in producing high performance composites, which outperform superalloys, is assessed.
