Titanium anode for cathodic protection
Cathodic protection is an anti-corrosion method based on the principle of electrochemical corrosion. The American Association of Corrosion Engineers (NACE) defines cathodic protection as reducing the corrosion rate by applying an applied electromotive force to shift the corrosion potential of the electrode to a lower oxidation potential. External current cathodic protection (ECCP) is to make the cathodic polarization of the protected metal by applying cathodic current to the protected metal through an external DC power supply. This method is mainly used to protect metal structures in large or high soil resistivity soils. Auxiliary anode is an important part of the external current system. Its function is to transfer the protective current through the medium to the protected structure surface. Auxiliary anode materials have been developed from scrap iron and steel anodes to mixed metal oxide anodes.
