Protecting Nickel Plated Steel from Zinc Chloride

April 20, 2015

Q. 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 ZnCl2 and I am trying to prevent the ZnCl2 from reacting with the metal whilst keeping the lining of the can conductive.
Can this be achieved by paint or other form of coating ?

A. Hi Mike. I'm not understanding the relationship between the graphite and protecting the can from the ZnCl2. Why graphite? I think a good electroless nickel plating on the steel would stand up to ZnCl2, while being conductive. This is a water-based solution? What concentration or molarity?

I think solid graphite construction might work as well. Then again I don't really understand your proposition. Good luck.
