The polarization potentials of anode and cathode, when iron was electrolyzed with an electro-chemical machining equipment in various solutions were measured by the reference electrode of metals.
The results obtained were summarized as follows.
1) It was found that the polarization potentials of anode were controlled by specific resistance of the electrolytes, when iron was activly dissolved in the electrolytes.
2) It was also found that the time for keeping the anode potential during the active dissolution of iron in sulfuric acid solutions was affected by convection of the solutions.
