“…In atmospheres polluted with chlorides the corrosion of carbon steel proceeds in local cells which resemble the sulphate nests mentioned above [76] . They may arise around chloride particles deposited on the surface, where the concentrated chloride solution locally destroys the FeOOH passivating film.…”

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).

“…This region is a mixture of several phases such as magnetite (Fe 3 O 4 ), hematite (a-Fe 2 O 3 ), limonite (g-FeOOHÁnH 2 O) and ferric hydroxide [Fe(OH) 2 ] [19]. The a-phase at this wave number was more distinctly seen with a broad and sharp peak during the early exposure period.…”

The corrosion behaviour of low carbon steel exposed to marine atmospheric, splash and immersion zones has been systematically studied by exposing steel specimens for a period of 12 months at the boat basin corrosion station of Chennai harbour, Chennai, Tamil Nadu, South India. The literature on similar work has been thoroughly reviewed which led to the initiation of this study for the first time at this harbour. The corrosion product (rust) on the specimens at 1, 2, 3 and 12 months was obtained and characterized by Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) analysis. Acaganeite was the rust phase identified in the splash zone as revealed by the FT-IR and XRD analysis. The other dominant phases were lepidocrocite, goethite and ferroxyhite. Small amounts of magnetite were also found to be present. The transformation of phases was observed in this investigation and discussed. A remarkable difference in the FT-IR and XRD patterns of the corrosion products at the splash and immersion zones were noticed and the corresponding phases formed were reported in this paper. The rate of corrosion in all the three zones was compared.

“…[5][6][7][8][9][10][11][12][13][14][15][16][17] Rust layers often form on the surface of steel structures experiencing a corrosion process, and the associated corrosion performance is dependent on a number of factors including rust formation, rust evolution and the inherent properties of the rust layers such as composition and structures. If pitting corrosion of HSLA steel occurs after prolonged exposure in the marine splash zone, as observed in R. Jeffery et al's exposure tests, 4 it can be speculated that the rust layer may contribute to the origins of pitting corrosion.…”

Corrosion Performance of High Strength Low Alloy Steel AISI 4135 in the Marine Splash Zone

The corrosion behavior of high strength low alloy AISI 4135 steel was studied following extended exposure to a Qingdao field environment. When electrochemically active γ-FeOOH was formed in conjunction with easily reducible β-FeOOH, these corrosion products acted to accelerate corrosion attack in the marine splash zone (i.e., steel structure above the water line that is splashed by sea spray). It had also been observed that the pH beneath the rust layer exhibited a minimum during the non-splash part of wet and non-splash corrosion cycling. These acidic conditions contributed significantly to an increase in the rate of localized corrosion, both beneath the rust deposits and within rust cracks and voids within pockets of rust deposits over the steel surface.
