Nanocoating and Electrospraying Techniques Used for Corrosion Mitigation of Aluminum in Nitrogen dioxide Environment
Abstract: Nitrogen gas absorbs moist air to produce nitric acid. It develops acidic medium for aluminum. It forms a corrosion cell on the surface of aluminum. The formation of corrosion cell is written as: Al|Al+3||H+|H2 thus Corrosion reactions accelerate on aluminum surface and Al is oxidized into Al+3 and the H+ ions is reduced into H2. This acid produces various forms of corrosion in aluminum like galvanic, pitting, stress, crevice, blistering, …
