The atmospheric corrosion of mild steel is an extensive topic that has been studied by many authors in different regions throughout the world. This compilation paper incorporates relevant publications on the subject, in particular about the nature of atmospheric corrosion products, mechanisms of atmospheric corrosion and kinetics of the atmospheric corrosion process, paying special attention to two matters upon which relatively less information has been published: a) the morphology of steel corrosion products and corrosion product layers; and b) long-term atmospheric corrosion (>10 years). KeywordsAtmospheric corrosion; Mild steel; Long-term; Morphology; Review. corrosión atmosférica del acero suave resumenLa corrosión atmosférica del acero suave es un tema de gran amplitud que ha sido tratado por muchos autores en numerosas regiones del mundo. Este artículo de compilación incorpora publicaciones relevantes sobre esta temática, en particular sobre la naturaleza de los productos de corrosión atmosférica, mecanismos y cinética de los procesos de corrosión atmosférica, prestando una atención especial a dos aspectos sobre los que la información publicada ha sido menos abundante: a) morfología de los productos de corrosión del acero y capas de productos de corrosión, y b) corrosión atmosférica a larga duración (> 10 años).

Corrosion resistance of metalized layers on steel parts in ventilation mill

et al. 2018

Corrosion behavior of metalized layers, obtained by Plasma Transferred Arc (PTA) process and by High-Velocity Oxygen Fuel (HVOF) process with the purpose to improve the wear resistance of vital parts of ventilation mill in a thermal power plant, has been tested. The test is performed using three electrochemical techniques, in a solution containing chloride and sulfate ions. It is shown that the steel surface (base metal) dissolves uniformly, without pitting or other forms of local dissolution. Morphology of metalized layers surface indicates that dissolution is non-uniform, but it still can be considered as general corrosion. The corrosion rate of base metal and metalized layer obtained by PTA process is rather low, while the corrosion rate of the metalized layer obtained by HVOF process is much higher. Also, the difference in corrosion potentials between the base metal and the HVOF layer is pretty high but slightly less than maximum allowed difference (prescribed by the standard), to avoid excessive galvanic corrosion. The values of corrosion rate obtained by different electrochemical techniques are in excellent agreement.

“…Indeed, iron oxides are the most commonly used colored pigments in the paints and coatings market [13]. It is also widely studied for the alloys and steel industry [14], in metallurgy [15], as catalysts [16][17][18] and photocatalysts [19], for magnetic storage devices, cathodes for primary and secondary batteries [20], chemical flame suppressant [21] and for the crucial industrial, economical and environmental issue of corrosion [22]. The thermodynamically stable crystallographic phase of ferric oxides is hematite (cc-Fe 2 O3) which represents the most important ore of iron considering its high iron content and its natural abundance.…”

Large arrays of perpendicularly oriented anisotropic nanoparticles of ferric oxyhydroxide (Akaganeite, P-FeOOH) and oxide (Hematite, (x-Fe 2 0 3 ) of typically 3-5 nm in diameter, selfassembled as bundles of about 50 nm in diameter and of up to 1 Pin in length have been successfully grown onto polycrystalline substrates without template and/or surfactant by heteronucleation from an aqueous solution of ferric salts and their optical and electronic properties investigated.
