Hi ,

I am looking to coat the inside of a small nickel plated steel can (about the same size as an AA battery casing) with a conductive graphite layer that has enough density to prevent ZnCl2 (zinc chloride) reacting with the steel.
The can is filled with some ZnCl2 and I am trying to prevent the ZnCl2 from reacting with the metal whilst keeping the lining of the can highly conductive.
Can this be achieved by paint or other form of coating ?

Thanks Mike

Hi Mike,
graphite usually serves as a permeable material, for instance to adsorb gases. It wouldn't be my spontaneous choice for a corrosion barrier.
What about a noble metal on the steel? Nickel isn't bad, but chlorides are corrosive. Could you afford thin gold, preferably over the nickel? If yes, it's generally the easy solution.
