*Also referred to as "Galvanic Protection" although this is more of a technique OF Cathodic Protection
*Allows for Oxidation to be sort of "rerouted" to a remote [[Sacrificial Anode]] and thus making the structure into a sort of [[Electrochemical Cell]]
*This is often done with a [[Zinc Sacrificial Anode]], but technically [[Galvanisation]] also uses the same mechanism (althouh it isn't often referred as Cathodic Protection in everyday use to provide more clarity)
*Most Boats use this for propellors, and other water exposed metals
*This is also very common for [[Pipeline Transport]] due to the expense of replacement
*Rebar is another use case
*The [[Sacrificial Anode]] can be directly attached (Usually via screws/bolts onto a clear surface), or remote via wires
*It is thus easily exchangable
*The [[Sacrificial Anode]] is gradually spent as it is oxidised, and thus must occasionally be replaced
*This does lead to more [[Lifelong Design]] when compared to simple galvanisation (Need to research how it compares to stainless steel etc)

=Methods=
==Galvanic==
*[[Galvanisation]] or use of a [[Sacrifical Anode]]

==Impressed Current==
*An "Active system" uses current flow to accomplish the goal

==Hybrid Systems==
*Uses both galvanic and active methods

*[[Protective Metal Coatings]]
