Abstract

PURPOSE: To economically hold a product to be protected at protection potential over a long term by connecting the product and an opposite insol. electrode to the cathode and anode of a galvanic anode power source, respectively, and charging an electrolytic soln. between the product and opposite electrode to form a closed circuit.
CONSTITUTION: Product 3 to be protected and opposite insol. electrode 5 are connected to the cathode and anode of galvanic anode power source 6, respectively, and electrolytic soln. 7 is charged between product 3 and electrode 5 to form a closed circuit. Product 3 is held at protection potential. This method replaces an expensive power source unit required for outer power source methods with cheaply usable power source 6, and opposite electrode 5 is made of insol. anode material to prevent contamination of soln. 7. Since the potential of power source 6 is determined with a pair of metals combined, overprotection is avoided. Problems such as waste of protection current and overprotection are solved with outer power source 6, making an automatic controller unnecessary.
