Sacrificial Anode in a not so Dry World

Sacrificial Anode in a not so Dry World

Sacrificial Anode in a not so Dry World

(OP)
  Will a sacrificial Zinc or Magnesium anode connected to a steel tank holding steel alloy parts provide rust protection for these parts while they remain in the tank ?
 
I would think that the steel parts would provide a low resistance path and become negatively charged by the zinc.  Can moist air be considered a weak electrolyte in this case?


RE: Sacrificial Anode in a not so Dry World

Yes, the anodes *can* protect things inside the tank, if it's got liquid water inside and the anodes are in the water too.  How much protection you'd get depends on a bunch of factors.

But moist air is NOT an electrolyte.
