To prevent electrochemical corrosion, hull anodes, collar anodes and rudder anodes should be attached to the underwater ship hull of metal ships, and metal ship propellers, shaft devices, rudder shafts, bow thrusters or keels. An anode consists of a less noble metal than the ship hull, so it oxidizes, i.e. it releases electrons into the water. The ship hull absorbs electrons and does not oxidize. Due to oxidation, galvanic anodes are consumed or sacrificed over time and must be replaced after a while. For this reason, they are frequently named …
