A method for electrodepositing a coating/free-standing layer on a workpiece in an electrolytic cell includes moving the workpiece and an anode applicator tool having a consumable anode insert relative to each other; anodically dissolving a metal from the insert and cathodically depositing the metal on the workpiece; providing flow of electrolyte solution through the insert to ensure that greater than 90% of the anodic reaction is represented by dissolution of the metal; recirculating collected electrolyte solution exiting the electrolytic cell through the insert; applying an electric current to the electrolytic cell; maintaining a concentration of the anodically dissolved metal within &#xb1;25% of each Ampere-hour per liter of electroplating solution; and creating a cathodic electrodeposit on the workpiece which includes the anodically dissolved metal, the chemical composition of the deposit varying by less than 25% in the deposition direction over a selected thickness of up to 25 microns of the deposit.

Porous, flow-through consumable anodes for use in selective electroplating

Anode applicators include consumable anodes, that can be operated in a non-stationary mode and are insensitive to orientation, are used in selective plating/brush electrodeposition of coatings or free-standing components. The flow-through dimensionally-stable, consumable anodes employed are perforated/porous to provide relatively unimpeded electrolyte flow and operate at low enough electrochemical potentials to provide for anodic metal/alloy dissolution avoiding undesired anodic reactions. The consumable anodes include consumable anode material(s) in high surface area to reduce the local anodic current density. During electroplating, sufficient electrolyte is pumped through the consumable anodes at sufficient flow rates to minimize concentration gradient and/or avoid the generation of chlorine and/or oxygen gas and/or undesired reaction such as the anodic oxidation of P-bearing ions in the electrolyte. The active consumable anode material(s) can have a microstructure which is fine-grained and/or amorphous to ensure a uniform anodic dissolution.

Flow-through consumable anodes

Super-hydrophobic and self-cleaning articles produced by imprinting exposed surfaces with suitable fine-grained and/or amorphous metallic embossing dies to transfer a dual surface structure, including ultra-fine features less than or equal to 100 nm embedded in and overlaying a surface topography with macro-surface structures greater than or equal to 1 micron are disclosed.
