Electrodeposition – one of the most commercially successful and inexpensive deposition methods – allows the fabrication of composite materials with feature sizes ranging from nanometers to micrometers. This method continues to attract a great deal of attention for the preparation of composites for structural and functional applications. This chapter presents an overview on the electrodeposition of composites. The fundamentals of electrodeposition are first presented. A concise account on the developments in the processing, properties, and applications of electrodeposited nano- and microcomposites is then given.
