Possibility of electroforming platinum or rhodium tubes  

+++

I'm searching for micro tubing with a very high corrosion resistance. Is it possible to electroform platinum or rhodium tubing with an OD smaller than 0,15 mm and a length between 10 and 20 cm.

I would certainly hesitate to say that it's impossible, but to get a reasonably thick deposit of either, with anything like acceptable properties in the way of stress and freedom from porosity is difficult. Any chance that gold would be sufficiently corrosion resistant? The electroforming of those tubes from gold sounds a hundred times easier.
