I am not sure where to put this but anyways, maybe someone here has had the experience and can tell me more about what important things would be necessary to do this. I am looking forward to making some electrical contacts that will have to survive a mercury environment in a sealed inert atmosphere container. My main conducting metal is copper but the part that will touch mercury will create an amalgam so I need to use a coating that is compatible with mercury so probably palladium or platinum for good contact resistance.
In general I am informed about the main steps of electroplating and also have some of the tools necessary.
I guess the main question is how do I get the necessary solution into which the target metal is dispersed and where I can then insert my copper parts and using low voltage DC create the electroplating itself.
I have seen people on youtube take and old harddrive disc dilute off the platinum coating from the disc and then put their parts inside the solution and electroplate them, maybe there is a trusted place where I can simply buy small quantities of forementioned metals?
videos like these make it seem easy but they don't explain the chemicals used in each step and their solution
thanks.
