ABSTRACT
Electrolytic deposition is achieved by electrolysis of aqueous solutions of simple or
complex salts containing metal ions to be deposited. Piece is coated cathode and anode current source can be an unassailable metal inert (insoluble anode in electrolysis) or metal coating, which dissolves as ions in solution (soluble anode in electrolysis), moving and discharged (submitted) at the cathode, forming protective metal layer. Electrolyte (electrolytic bath) includes: a metal compound which decomposes and is deposited in well-defined concentration, buffering agents to maintain constant acidity (pH) solution, inorganic substances to increase the electrical conductivity and special additives to improve porosity, adhesion, gloss coating or structure. Because of qualityprice- performance ratio and outstanding qualities they possess, composites allow multifunctional pieces, shape simplification mechanisms and improve performances. Layers of composite materials made by deposits fall into the category of advanced materials. Metal matrix composites studied in this paper have the particularity that the matrix is an electrodeposited metal or alloy.

Keywords: electrodeposition, cathode, anode, layer, metal, alloy, conditions.
