Impressed current vs galvanic anode
WitrynaThe galvanic anodes are self-regulating in nature and supply output current based on the corrosion rate of the steel rebars. ... HYBRID ANODES FOR ACCELERATED … WitrynaThere are two types of cathodic protection: galvanic anode and impressed current cathodic protection. Both provide a cathodic protection current flow from cathodic protection anodes placed within the same electrolyte as the metal to be protected. The current flows from the anode into the electrolyte.
