Mini Cathodically-Protected steel plate

AI Thread Summary
Bolting a steel plate to a zinc plate without an interface can work for cathodic protection, especially when seawater is present as an electrolyte. The seawater facilitates ion transfer, which is essential for effective cathodic protection. While the setup may seem simple, it is crucial to ensure that the electrolyte is adequate for the process. Additionally, cathodic protection can be costly in terms of materials and maintenance. Overall, using a sacrificial anode like zinc in the presence of seawater should provide sufficient protection.

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.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
