Ruthenium plating is another option I'm considering. I've read that ruthenium is inert to *most* other chemicals, but can't find anything referring specifically to salt. Can anyone here confirm that ruthenium won't be corroded by salt? I have Leaving Cert level chemistry, but don't want to rely on my own inexpert opinion & end up making a very expensive but useless item!

Thanks for your help!
