Will the ERPS system work on Land Rovers or other vehicles with aluminium panels to prevent bimetallic (dissimilar metal) galvanic corrosion?
With aluminium panels the system works in exactly the same manner as with a steel panel, slowing the oxidisation process. As long as the aluminium is painted the system will set up a negative charge on that panel. Wherever two or more dissimilar metals come in contact with each other in the presence of an electrolyte (eg: water), a small galvanic cell is produced causing rapid acceleration of corrosion. This is the case with the Land Rover where you have both steel and aluminium in close proximity, the system will however counteract this affect by inducing a negative charge to work against the galvanic reaction.
