Stainless Steel in Contact with Other Metallic Materials
www.worldstainless.orgIf galvanic corrosion occurs, the less no-ble material – the anode – is preferentially attacked whilst the more noble material – the cathode – is even protected against corrosion. In fact, the principle of cathodic protection isbased on sacrificial anodes providing protection from corrosion. The contact of two metals with different
Cathodic Protection Field Installation Guide-NEW
www.usbr.govCathodic protection is a means of reducing corrosion of a metal by artificially causing direct current to flow from external anodes, through the electrolyte (soil or water), and onto the structure to be protected. The two types of CP systems are galvanic anode and impressed current. Galvanic anode CP systems provide cathodic current by galvanic ...

These include an anode (where corrosion or chemical oxidation reactions are taking place), a cathode (where chemical reduction reactions are taking place), an electrolyte (solutions or conductive media providing the supply of chemicals needed to sustain the cathodic reactions at or near the metal surface), and a metallic path.

The crevice area itself becomes the anode, and thus the preferred region for metal dissolution. (see Fig. 7). It may also occur under washers or gaskets, when the entry of water underneath is not prevented (see Fig. 7).
