Mini Cathodically-Protected steel plate

    Mini Cathodically-Protected steel plate....

    Hi guys/gals:

    I am doing a project on cathodic protection. If I have a steel and zinc plate, does bolting them together with nothing at the interface suffice as Cathodic Protection? It looks too simple to be true. So I need your help to validate the above method.

    Thank you!

    You need something to trasnfer the ions between them - like sea water.
    Of course if you didn't have the water you wouldn't need the protection!

    Cathodic protection is simple, it's just expensive in materials and replacement effort.

    Oh yes. I forgot to mention that the electrolyte will indeed be present (seawater). So are you saying that my set-up will be alright? Like I said, I worry that my experiment sounds too simple.

    Thanks

    I think it may be the same as the process of electrolysis that need a liquid the is conductor of electricity... like some solution to transfer the ions between steel plate and zinc plate...

    You should be fine if your form of protectioon is via a sacrificial anode. There is another form of cathodic protection.
