Abstract
Microbiologically influenced corrosion (MIC) is defined corrosion due to the presence and activities of microorganisms. Microorganisms produce localized attack including pitting, enhanced erosion corrosion, enhanced galvanic corrosion and stress corrosion cracking. Microbiologically influenced corrosion has been reported for all engineering metals, nonmetals and alloys. The industries most affected by MIC are power generation; oil production, transportation, and storage and water distribution. General environmental factors such as rainfall, soil moisture, temperature and topography are known to affect the corrosion rates. Electrical industry which is located in environmental harsh condition such as high temperature and moisture is affected by MIC. It should be noted that, management, control and inhibition of MIC is more important topic than bio-corrosion. To inhibit MIC, coating methods have been widely used because of their effectiveness, ease of application, and low cost. Organic coatings are employed to protect structural materials in industry against corrosion. Nanomaterials alter protective performance of organic coating with multifunctional characteristics rising from the distinctive features of them. Titanium dioxide (TiO2) nanoparticles are inhibitive elements with a strong oxidation power. TiO2 nanocomposite with other metal oxide nanoparticles such as ZnO, ZrO2 and CuO improve MIC inhibition and organic coating properties. These coatings with metal oxide nanocomposites as nanofillers could deliver a promising approach for anticorrosion and antibacterial in electrical industry.
