SYSTEM ZUR KONTROLLE VON KORROSION DURCH DUENNE SCHICHTEN KORRODIERENDER FLUIDE.

摘要

A layer (12) of an absorbent material for absorbing the corrosive fluid is disposed on the metallic surface (10a). A counterelectrode (14) is located within or adjacent to and in electrical contact with the absorbent material (12). An electro-chemical potential control means (22) is connected in circuit with the counterelectrode (14) and the metallic surface (10a) for maintaining the potential of the metallic surface (10a) by passing a current between the counterelectrode (14) and the metallic surface (10a) through the corrosive fluid in the absorbent material (12). The system may further include a reference electrode (18) for more precise control of the potential, and a poorly conducting, or insulating but interrupted layer (24) between the layer (12) of absorbent material and the metallic surface (10a).
