Definição

• Cathode.  The negative electrode in the electrogalvanic or electroplating process; the opposite of the anode. The piece being worked on (called the work) is the cathode – the pattern to be electroformed or the piece to be plated; it is wired to complete the electric circuit. Metal builds up on the cathode as it passes through the electrolyte solution from the anode.  See electrolysis.
