Abstract
A process for the selective variation in density of particulate matter codeposited within metallic matrices deposited onto articles utilizing increased levels of rotation of said articles during plating cycle to attain said selective codeposition density. The attainment of varying densities of codeposited particulate matter in the plated layer along the surface of the substrate is particularly useful in cost reduction and improved product performance.
Claims13
A process for plating a substrate to form a composite plated coating on a surface thereof said process comprising contacting said surface of said substrate with a plating composition incorporating particulate matter insoluble with said plating composition to yield a composite plated coating on said surface with said particulate matter dispersed within said coating, said coating having a predetermined varied density of codeposited particulate matter from a first region along the surface of the substrate being plated to a second region thereof, said predetermined varied density of codeposited particulate matter between said first and second regions being achieved by continuously rotating said substrate during the plating process at a speed greater than that necessary to achieve a different varied density of codeposited particulate matter within said coating between said first and second regions.
A process for plating a substrate to form a composite plated coating on a surface thereof said process comprising contacting said surface of said substrate with a plating composition incorporating particulate matter insoluble with said plating composition to yield a composite plated coating on said surface with said particulate matter dispersed within said coating, predetermining a varied density of codeposited particulate matter from a first region along the surface of the substrate being plated to a second region thereof, selecting a speed of rotation of said substrate for the plating process to achieve the predetermined varied density of codeposited particulate matter, and continuously rotating said substrate during the plating process at the selected speed to achieve the predetermined varied density of codeposited particulate matter within said coating between said first and second regions.
