METHOD AND APPARATUS FOR ELECTROPLATING

摘要

A method and apparatus for electroplating at least a part of the surface area of an article (10) with a metal coating is described, the method including the steps of: placing the article (10) in a vessel (30), the vessel being provided with means to allow access (38) of fluid to an interior volume, said article being contained in said interior volume and, means to allow egress (40) of said fluid; providing said vessel with anode (42) and cathode means such as to enable said article to become cathodic with regard to an anode (42) extending into said interior volume; providing means to cause at least two different fluids including at least one plating electrolyte solution to be introduced into the vessel (30) in sequence, flow through said interior volume and to exit therefrom for a sufficient time to allow a required thickness of said metal coating to be deposited.
