Abstract
In this paper the development and application of new MnOx coated electrode on metal oxidized substrate for alternative energy device have been described. It has high thermal and corrosion resistance under the influence of strong electric fields. In addition, the decomposition of heat carriers, especially water, not occur on the electrode surface during the operation of the heater, since the result of water splitting is an explosive mixture (H2+O2). Considering the capability of Mn3+ / Mn4+ redox system to provide high-speed cycling of electric charge at potentials significantly is lower than the water splitting potential. Simple carbon steel was used as the substrate. The MnOx film was deposited electrochemically from an electrolyte containing monobasic carboxylic acids. Mixed electroneutral complexes [Mn(L)2(H2O)4] formation ensured the deposition of MnOx-based composite at low potentials. The corrosion resistance of the obtained composite films was very high. The phase composition and morphology of electrolytic MnOx films have been characterized using X-ray diffraction, scanning electron microscopy and thermogravimetric study. The industrial tests of the developed Fe, FeOy/MnOx electrodes showed their ability to work for at least 10000 hours. The developed electrodes were introduced into the industrial production of electric boilers "Energy" with direct heat carrier heating of various capacities, which are used in residential premises and other facilities. Their long-term operation confirmed their high performance characteristics.
