Project Description


  • MTI is assessing the anti-corrosive properties of inorganic layers applied on hydraulic cylinder rods for the protection against wear and corrosion.
  • The objective of this project is to develop the Electrochemical Impedance Spectroscopy (EIS) measurements into a reliable and fast tool for this purpose.

M2i Project:

  • Evaluation performance of several coating systems and substrates by electrochemical testing and exposure to a simulated tidal zone.
  • Defining a robust and fast procedure for EIS measurements.

Industrial Benefits:

  • Dedicated procedure for pre-screening the quality of noble inorganic coatings on carbon steel used in a marine environment.
    Clear distinction between poor and good performing systems.
  • Cost savings due to prevention of early corrosion failures amount to 0.6-0.9 million EUR/year.
