Corrosion testing can be used to great advantage when developing new materials, selecting materials for structures, quality assurance and analysis of failure and damage. Corrosion testing can be performed under realistic conditions; in field or operating trials or in a laboratory setting.
Swerea has a broad offering for testing in the field and under operating conditions. To acquire fundamental knowledge of metallic corrosion, electrochemical analyses are usually conducted. Swerea has an electrochemical laboratory that is equipped for conventional electrochemical testing including corrosion potential and polarization curves, as well as local electrochemical techniques.
Testing at field stations
We have field stations for testing in different atmospheres, in seawater and in different soils. Our atmospheric field stations cover most environments and are located in many locations in Sweden and abroad. Exposure testing in seawater can be performed in our locations on the west coast of Sweden and on the Atlantic coast in Brest, France. For testing exposure in a range of soils we have access to eight testing locations throughout Sweden.
Testing in the laboratory
For atmospheric corrosion testing in the laboratory we have a large number of climate chambers and salt spray chambers. For corrosion testing of materials for high-temperature applications we have a high-temperature lab that is equipped with various types of furnaces for exposure testing. We also have autoclaves for corrosion testing of materials that are used in chemically aggressive environments, for example, in lye, organic acids and fuels.
We perform corrosion testing in research projects and in company-specific commissioned R&D work.
