Can a cathodic protection system still work if there is no current between the anode and cathode?

  • $\begingroup$ Yes I think it can be done but problem is that the process would become slow and less effective so we need a current also to overcome driving forces. $\endgroup$ – Physicsapproval Jun 10 '17 at 3:04
  • $\begingroup$ By definition, cathodic protection relies on the electric current to prevent (or redeposit) the protected metal. For example, galvanized iron is protected by the dissolution of zinc and the current that generates. $\endgroup$ – DrMoishe Pippik Jun 12 '17 at 0:58
