Abstract

Recent technological trends in electrodeposited metallic coatings are examined by reviewing the following areas of metal finishing which can be considered to be directly relevant at present: (i) Replacements for hexavalent chromium-based coating processes. (ii) Electrodeposited composite coatings. (iii) Compositionally modulated or layered coatings. The replacement of chromates is an environmentally-driven problem and one which has yet to be achieved, although certain lower toxicity systems are showing promise. Composite coatings have been available commercially since the 1960s and represent a powerful method to enhance surface properties - particularly hardness and wear resistance. Compositionally modulated or layered coatings are at
