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