ELECTROCHEMICAL CODEPOSITION OF INERT PARTICLES IN A METALLIC MATRIX

A survey on electrochemical codeposition of inert particles in a metal lic matrix is given. Particles held in suspension in an electroplating bath are codeposited with the metal during electrodeposition. The par ticles used are inert to the bath and can be of different types, that is, pure metals, ceramics or organic materials. Combining this variety of types of particles with the different electrodeposited metals, ele ctrochemical codeposition enables the production of a large range of c omposite materials with unique properties. Many experimental factors w ere found to influence the codeposition process, which led to some und erstanding of the mechanism. Models to predict the codeposition rate w ere developed, but were only partly successful.
