what is anode sludge
This excessive anode sludge, hereinafter referred to as anode sludge, is usually seen as an excessive quantity of copper particulates which have corroded from the anode or anodes and settled into the tank or anode bag. Anode sludge indicates that something is wrong in the plating process.or current to flow, copper ions will be dissolved from the anode and deposited on the cathode, as electrons flow in the opposite direction. We visualize that copper is dissolving from the anode in proportion to the current density, according to Faraday's Law, in a smooth and uniform manner.
