Abstract
Electroplatings, as applied to improving the appearance and corrosion-resistance of the metals used in the construction of motor cars, bicycles, domestic appliances, &c., is a process with which everyone is familiar. It is not so widely known that electrodeposited coatings play an important and expanding role in the engineering industries, not only for providing corrosion protection but also for restoring to plan size worn or overmachined components (“building-up”) or for modifying the surface properties of the component for some specific purpose, e.g. to increase the surface hardness and thereby promote wear-resistance. These engineering applications of electrodeposition are very largely confined to the treatment of steel components and, probably for this reason, there are relatively few references in the literature to the effects of plating on the mechanical properties of non-ferrous materials. For the most part, therefore, this review deals with steel as the substrate.
