SYSTEM FOR CONTROLLING CORROSION IN THIN LAYERS OF CORROSIVE FLUIDS

摘要

A system for preventing corrosion of a metallic surface by a thin film of corrosive fluid. The system comprises an absorbent material for absorbing the corrosive fluid. The absorbent material is disposed on the metallic surface. A counterelectrode is located within or adjacent to and in electrical contact with the absorbent material. An electrochemical potential control means is connected in circuit with the counterelectrode and the metallic surface for maintaining the potential of the metallic surface by passing a current between the counterelectrode and the metallic surface through the corrosive fluid in the absorbent material. The system may further include a reference electrode for more precise control of the potential.
