Abstract
Corrosion protection systems which make use of a barrier which is placed between a corrodible substrate and a counter-electrode. The barrier can provide more uniform current distribution on the substrate, and/or enable the counter-electrode to be more easily maintained or replaced, and/or reduce the rate at which the current density on an elongate electrode changes with distance from the power source, and/or provide a controlled environment around the electrode to improve its efficiency.
