Corrosion risk analyses

MONITORING AND ANALYSIS OF CORROSION:

  • Electrochemical measurements of material properties, e.g. polarization curves, coulometry, pitting tests
  • Electrochemical methods: galvanic measurements, impedance measurement, polarization resistance measurement => determination of corrosion rate, definition of material resistance in given environment, etc.
  • Machu test: accelerated corrosion test in an ultrasonic bath
  • Complex corrosion analysis, including: corrosion damage simulation, definition of possible risk points, corrosion risk assessment, optimization of component design, corrosion inhibitor effectiveness verification (e.g. CSN EN 480-14)
  • Designing solutions to minimize the risk of corrosion products

 

ELEKTROCHEMICal measurements:

VZLU laboratories are equipped to perform electrochemical measurements and determination of corrosion properties of materials. The Voltalab PGZ 100 allows the measurement of material properties, i.e. polarization curves, coulometry, pitting tests, polarization resistance, etc. Thanks to a special measuring cell for the measurement of a thin layer of electrolyte, it is possible to simulate and measure corrosion behavior in atmospheres near atmospheric corrosion. From the measured Tafel curves, it is possible to determine the effectiveness of corrosion inhibitors to monitor the effect of inhibitor concentration on corrosion rate reduction.
