A CONTINUOUS-ACTION REFERENCE ELECTRODE FOR THE CATHODIC PROTECTION OF METALLIC STRUCTURES

摘要

The invention relates to the field of cathodic protection of underground or underwater metallic structures. The reference electrode object of the invention has a plate-shaped support (1) made of porous ceramic material on which support (1) flat faces copper plates (2) alternated with titanium plates (3) or with nickel-based alloy plates are applied by means of plasma-coating or potting. The copper plates (2) are isolated from the nickel plates. On one of the lateral faces of the porous ceramic support (1) a metal membrane (6) is applied, constituting an electrochemical potential transducer.
