Abstract
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. Atmospheric corrosivity is one of the parameters characterizing the technical condition of airfield pavement functional elements; it makes it possible to estimate a suitable frequency of airfield periodic inspections. Assessments of concrete corrosion and atmospheric corrosivity enable appropriate countermeasures to be taken in order to maintain the airport functional elements in a constant state of technical readiness. In the following study, the prepared samples were exposed to atmospheric conditions in designated places located at selected military airport facilities. Corrosion samples in the form of 50 mm × 100 mm standard samples, 1 mm to 3 mm in thickness, were placed on special frames located within fenced corrosion stations. The corrosion rate rcorr of a specific metal, expressed as a corrosion loss, depends on the environmental conditions. This article presents an atmosphere corrosivity category assessment for low-carbon steel, zinc, copper and aluminum reference samples, taking into account weight or thickness loss after one year of exposure.
Highlights
Atmosphere corrosivity is one of the parameters characterizing the airfield pavement’s technical condition of the airport functional elements
While nondestructive techniques of corrosion detection are gaining popularity [23,24], the atmosphere corrosivity parameter may be one of the elements on the basis of which it is possible to determine the degree of pavement deterioration, according to the level of corrosion of reinforcing steel, and considering the corrosion of cement concrete in specific corrosive atmospheric conditions
The developed system of atmospheric corrosion assessment is designed to support the process of managing functional elements of military and civil airports by analyzing the parameters characterizing atmospheric conditions and collecting data from atmospheric corrosivity tests
Summary
Atmosphere corrosivity is one of the parameters characterizing the airfield pavement’s technical condition of the airport functional elements. Concrete corrosion phenomena are related to processes in aircraft construction. Research in this field is based on analyses of the influence of atmospheric conditions on the technical conditions of airfield pavements [1]. A condition analysis in which the surfaces of an airport’s functional elements (EFL) are examined should be carried out taking into account the adverse influence of the atmospheric environment in which the pavement is used. Atmospheric environments differ in terms of insolation, temperature, humidity and the presence of pollutants [2]. Aircraft constructions with specific corrosion resistance in one respect may not be resistant in another
