David,

The only thing I found was a brief summary about a "gas plating" process sometimes used with tungsten. As other folks have pointed out, tungsten is not plated in a conventional aqueous process, but uses molten salt electrolytes or vapor deposition. It sounds like I'd be easier to wear a hole through a tungsten disc than to do any kind of relatively exotic plating processes.

Regards,

TIM

Is there more than one anode? This is quite confusing. You wish to place the einzel AFTER the anode, but make the anode a ring?

A diagram would be much appreciated.

Thinking about this, you might be able to "plate" tungsten at home using a variation of the way quartz-halogen bulbs work; At high temperatures, tungsten-halogen compounds break down, depositing metalic tungsten, at lower temperatures, halogens attack tungsten.

So you could put the electrode in a bulb with a chunk of tungsten, heat the whole thing up, making sure that the electrode was the hottest thing in there, and eventually that's where the tungsten would collect.
