Corrosion Testing

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.

Swerim 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.

Corrosion assessment at Swerim includes:

  • Expertise in corrosion of metallic materials and how corrosion processes occur via material-microstructure-corrosion interaction.
  • Electrochemical testing in different electrolytes over a range of temperatures and pressure, including measurement of the critical pitting corrosion temperature/potential as well as critical crevice corrosion temperature/potential in accordance with ASTM standards (e.g., ASTM G150 (in an Avesta cell), ASTM G61, ASTM G48).
  • Autoclave testing for corrosion exposure in aggressive environments at high temperature and pressure.
  • Customised testing. Swerim also carries out method development.
  • Field exposure testing.
  • Testing with respect to stress corrosion cracking (SCC) and hydrogen embrittlement (HE) with SSRT (Slow strain rate testing), constant load and TDS (Thermal Desorption Spectroscopy).
  • Measurement of localised corrosion on the micro/nanometre scale: Swerim is outstanding in localised corrosion testing linked to material microstructure using SVET (Scanning Vibrating Electrode Technique), SKPFM (Scanning Kelvin Probe Force Microscopy) and in situ AFM.
  • Advanced material and surface characterisation together with predictions of material behaviour through thermodynamic computations.

We perform corrosion testing in research projects and in company-specific commissioned R&D work.
