Abstract
In the result of Fe-Si grounding electrode characteristics investigation it was obtain, that the rate of anodic dissolution can be predicted by properties of thin film, formed preliminary. To determine the phase composition of the films is advisable to use the cathode recovery in hydrochloric acid electrolyte. Quantitative phase composition can be characterized by the potential recovery of the corresponding oxides. The share of the free surface can be calculated by tafelski factors anodic polarization dependences obtained by the method of pulse chronopotentiometry.
Keywords: ferrosilicon electrode; phase composition; part of free surface; rate of anodic dissolution; chronopotentiometric curves; the pressure sensor design.
