METHOD OF CORROSION PROTECTION OF OBJECTS IN CONTACT WITH CONDUCTING MEDIUM According to the method, polarizing current is periodically applied between the auxiliary electrode and the object to be protected from corrosion in order to maintain the latter's potential within prescribed limits. During the time intervals when the supply of polarizing current is discontinued, the auxiliary electrode (the cathode) is shorted out by the object being protected.
