| Summary: | The aim of this study was evaluation of atmospheric corrosion of structural
steel S235JR in an industrial environment. General corrosion testing was
carried out for six months in the field, at selected atmospheric corrosion
stations, near the Sulphuric acid plant, in the Electrolytic refining plant
and next to the automatic air quality monitoring station in the city of Bor,
Serbia. The results were compared with the standard specimens stored in the
laboratory. The steel S235JR specimens were characterized regarding
mechanical characteristics by tensile testing. With the aim of assessing the
mutual effect of corrosion and polluted industrial environment
meteorological parameters were also determined, as well as pollutants in the
atmosphere (mainly SO2). The X-ray diffraction method was used to identify
the composition of corrosion products. Research within this work enabled a
better understanding of the behavior of structural steel S235JR in which
there was a reduction in load capacity due to corrosion. The corrosion rates
obtained under each tested exposure condition showed noticeable differences.
It was found that depending on the content of pollutants in the atmosphere
and the location of the steel specimen, the corrosion products represented
different compounds and solid phases. |
