This paper is intended as an overview on platings for precision finishing operations. After a brief review of the two processes (polishing and precision machining) by which a coating on a part can be converted to a precision surface, the coatings which work successfully in these applications will be discussed. Then adhesion and stress aspects of deposits will be covered. Electroless nickel, which is a particularly attractive coating for precision finishing applications, will be discussed in some detail, from its early years as the "Kanigen" process to the present. Since microstructural changes in deposits are important for precision parts, this aspect will be covered for electroless nickel, copper and silver deposits. Lastly, some words will be directed at potential future electrodeposited coatings including nickel-phosphorus alloys, and various silver alloys.
