"FPMAGEL, I don't understand what a micro wind turbine has to do with galvanic protection. "
You only need about 200watts, for a coulpe of Ks(they didn't mention the pipe size), to protect it.
In general, a current is sent through a water/gas pipe, this stops the pipe reacting with the surounding dirt, this related to thread by the fact it
might stop oyxgen reacting with the graphite.

Well, as these are the electrodes, the plasma current is already flowing through them. So would they be protected when serving as the cathodes, or
anodes? In either case, one side still can't be protected.

AC current and high hertz should protect both. I don't know about what type you would need, high voltage or amps or both
What are you making?

Would the positive and negative cycles of the AC have that net effect in this case? I know that AC in HCl solution will dissolve most metals including
Pt. I doubt this is too different.

There's always DC bias in my case that exceeds the AC, so there's never a zero crossing. I see no way to implement galvanic protection; the answer's
in materials and geometry I guess. I'll try using larger microhollows, but I have to go to a jeweller as all my diamond bits have worn out from
drilling the sapphire (I was told to drill under water or the heat unbonds the diamond particles, but too late). Also, I don't know if larger
microhollows will work at all. All I've seen in the literature are sub-millimeter, and mine are already about a millimeter.
