Resumen
Abstract Atmospheric corrosivity is classified according to EN ISO 9223 Corrosion of metals and alloys – Corrosivity of atmospheres – Classification, determination and estimation. For the determination and estimation of the corrosivity category, standardized approaches are used. Monitoring of corrosivity with the application of various sensors is an actual trend. The paper gives results of verification of some types of sensors for this monitoring with standardized flat samples at atmospheric test sites in the Czech Republic. The trend of decreasing atmospheric corrosivity is evident in the las

Resumen
ISO 9223 can be used to categorize the corrosivity of atmospheres through either corrosion loss measurements or the use of environmental data. Although both methods are expected to give the same result, discrepancies have been found to occur. The present paper analyses this aspect of ISO 9223, focusing on the effects of metal composition, when using carbon steel, in corrosivity categorisation. Low and medium carbon steel were, therefore, exposed outdoors at one site in Mauritius to determine its atmospheric corrosivity. It was found that for medium carbon steel, the corrosivity obtained from c

The aim of this research is to assess corrosion in natural atmospheric conditions, based on exposure of material samples and periodic monitoring, and to determine the size of corrosion losses, their form and appearance, as well as changes in physical properties at regular time intervals. Atmospheric corrosion tests were ultimately carried out in order to determine the corrosion resistance of a cement concrete airfield pavement, as well as to assess the type of corrosion and research data in order to determine and estimate the corrosivity of the atmosphere.

The classification, assessment, and estimation of the atmospheric corrosivity are fixed by the ISO 9223 standard. Its recent second edition introduced a new corrosivity category for extreme environments CX, and defined mathematical models that contain dose–response functions for normative corrosivity estimations. It is shown here that application of the ISO 9223 standard to archipelagic subtropical areas exhibits major shortcomings. Firstly, the corrosion rates of zinc and copper exceed the range employed to define the CX category. Secondly, normative corrosivity estimation would require the m

Resumen
The knowledge of the first-year corrosion losses of metals (K1) in various regions of the world is of great importance in engineering applications. The K1 values are used to determine the categories of atmospheric corrosivity, and K1 is also the main parameter in models for the prediction of long-term corrosion losses of metals. In the absence of experimental values of K1, their values can be predicted on the basis of meteorological and aerochemical parameters of the atmosphere using the dose-response functions (DRF). Currently, the DRFs presented in ISO 9223:2012(E) /1/ standard are used for

Resumen
Atmosférická koroze a klasifi kace agresivity atmosfér je dlouhodobým předmětem studia SVUOM. Ve spolupráci s CGS byly v roce 2001 vytvořeny mapy korozních rychlostí a korozních tříd pro uhlíkovou ocel, patinující ocel, zinek, měď, bronz a hliník. Tento článek uvádí aktuální přístup k modelování atmosférické koroze v České republice, který je založen na modifi kovaných funkcích zahrnujících klimatická data, znečištění ovzduší a nově i vliv rozmrazujících solí v okolí dálnic.

Resumen
The first field data describing the dynamics of the carbonate system, aragonite saturation state, and CO2 fluxes between the ocean and the atmosphere in the Gulf of Anadyr in the late autumn season are presented. It was established that during this period the gulf waters absorbed carbon dioxide from the atmosphere at a rate of -22,5 mmol m‑2 day‑1, which determined the “classical” mechanism of seawater acidification due to uptake of excess atmospheric CO2. In general, surface waters of the gulf were supersaturated with respect to aragonite. The exception was the highly dynamic region of Anadyr

Resumen
Corrosion is one of the main causes of early failure of infrastructure both for public housing facilities and public facilities in downtown Langsa. This corrosion is caused by air pollution generated from motor vehicle and household industry exhaust fumes and exhaust smoke from the nearest palm oil mill industry from the city of Langsa. Related to air pollution, its sustainability should be a concern regarding environmental impacts that occur, one of which is atmospheric corrosion. This study aims to analyze the impact of the effects of pollution on infrastructure corrosion on construction ste

Resumen
As one of the factors (e.g., material properties, surface quality, etc.) influencing the corrosion processes, researchers have always been exploring the role of environmental factors to understand the mechanism of atmospheric corrosion. This study proposes a random forest algorithm-based modeling method that successfully maps both the steel’s chemical composition and environmental factors to the corrosion rate of low-alloy steel under the corresponding environmental conditions. Using the random forest models based on the corrosion data of three different atmospheric environments, the environme
