Preventing corrosion

Better product quality, cost savings and health & safety improvement

​VTT holds strong expertise on corrosion phenomena and prevention in a wide variety of applications and environments. We offer our customers high-quality knowledge and facilities for corrosion research, monitoring, modelling and prevention methods.

Corrosion is one of the most common and expensive challenges for a range of industrial fields. Preventing corrosion provides great savings in operation and maintenance costs, improves health and safety issues and ensures good product quality. Root-cause analyses provide means for proper material and system optimisation. Field studies and experimental work may be complemented with state-of-the-art computational modelling. Corrosion research combines sophisticated surface and metallurgical characterization techniques, electrochemical methods and microbiological analyses.

Examples of our core competence areas in generic and tailored corrosion research are:

  • Tailored field research based on customer’s needs
  • Comparison of material candidates and prevention strategies
  • On-line electrochemical monitoring techniques, monitoring of deposit formation
  • Corrosion prediction
  • Failure analysis


Examples of corrosion issues we have been working with:

  • General corrosion
  • Crevice and pitting corrosion
  • Environmentally-assisted cracking
  • Microbially induced corrosion, biofouling
  • Combined effects of corrosion and wear (tribocorrosion)
  • Atmospheric corrosion
  • Dealloying
  • High-temperature corrosion
