Striking an arc between a copper cathode and a tungsten anode can lead to copper deposition on the anode. The deposition rate can be calculated and is expected to be proportional to the current, though specific calculations may require expert resources for each metal. The feasibility of this process occurring through air or another gas is questioned, with references to cathodic arc deposition for further understanding. Overall, the discussion highlights the potential for metal transfer in arc systems and the need for precise calculations. Understanding these principles is crucial for applications in electroplating and related fields.
