ANODE UNIT FOR SYSTEM OF CATHODE PROTECTION AGAINST SEA CORROSION OF METAL SHIPS AND STRUCTURES Russian patent published in 1996 - IPC

FIELD: electrochemical protection against corrosion. SUBSTANCE: anode unit has dielectric base. There is a groove at central part of the base. Anode is mounted into the groove. Anode is made in form of a plate provided with current-leading rod. Monolithic dielectric base is made of strong isolation structural material, for example, of epoxy glass-reinforced plastic. There is external cladding layer on the surface of plastic; the layer demonstrates chemical resistance to active path of polymeric material, for example, fluoride-containing polymer. Plate of anode is made of bimetal material, for example, plate-niobium, or of ceramics, for example, magnetite or ferrite. It may also have active surface layer. Anode plate is installed onto the bottom of the groove from the top inside the base and is connected with it tightly. EFFECT: improved quality of protection. 6 cl, 2 dwg
