    摘要: 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.
