The laboratory performs model accelerated and electrochemical corrosion tests of metal, nanomodified materials and coatings; precision thermogravimetric (TGA) and differential scanning calorimetric (DSC) analysis simultaneously on the same sample.

Potential partners and clients of the laboratory are research teams with similar research interests and organizations working in the field of material science.

ACTIVITIES

  • Testing of metallic materials and coatings in artificial atmospheric conditions (salt fog, humid heat, etc.);
  • Determining the degree of destruction and the intensity of the manifested corrosion defects;
  • Electrochemical monitoring of corrosion processes;
  • Calculation of corrosion kinetics;
  • Combined TGA-DSC / DTA tests on samples from 5 mg to 2 g at a resolution better than or equal to 0.1 μg;
  • Measurements in a controlled atmosphere (eg Ar) with simultaneous heating of the analyzed sample and reference;
  • Identification of the gases released during heating during the thermal analysis and identification of their individual components by a quadrupole mass spectrometer.

SERVICES

  • Qualitative and quantitative assessment of the observed corrosion damage and defects.
  • Characterization of the kinetics of corrosion processes by:
    - Determining the mass loss per unit area;
    - Calculation of the corrosion rate over time;
    - Degree of damaged surface;
    -Shape and density of pitting
    -DSC / DTA analysis of liquids, powders, gels, solid samples, polymers, etc.;
    -DSC / DTA analysis to measure glass transition, phase changes, purity, evaporation, melting, crystallization, sublimation, polymerization, heat capacity, compatibility, pyrolysis, etc.
