The Electrochemical Testing Laboratory conducts electrochemical characterisation and testing of conducting and semiconducting materials, assesses corrosion resistance, and studies and optimises surface-modification processes (including direct-current and pulsed electrodeposition, plasma electrolytic oxidation – PEO, and electrophoretic deposition – EPD).
The laboratory is equipped with conventional potentiostat/galvanostat stations (CV, LSV, CA, CP, EIS) and a station for scanning electrochemical techniques (SKP, SVET, SECM, LEIS), enabling micrometre-scale mapping of local potentials, currents and impedance. This setup combines macroscopic measurements with local maps of electrochemical activity on material and coating surfaces under application-relevant conditions
Workshop equipment:
- SEW M370 scanning electrochemical workstation with PARSTAT 2273 module enables SKP, SVET, SECM and LEIS measurements, precise three-axis positioning and micrometre-resolution mapping of local currents, potentials and impedance. The PARSTAT 2273 extends the station’s capabilities with CV, LSV, CA, and CP techniques, while the integrated frequency response analyser (FRA) enables EIS measurements in the 10 mHz–1 MHz range; Mott-Schottky analysis is also available based on these data. The system is used for studies of corrosion resistance of bulk materials and coatings, evaluation of electrode performance, and analysis of surface modification processes.
- Autolab PGSTAT30 (up to 1 A) and PGSTAT12 (up to 250 mA) support CV, LSV, CA, CP, and EIS techniques. Both potentiostat/galvanostat systems are equipped with an FRA module and GPES/FRA software. Applications include electrocatalysis studies as well as corrosion tests of materials and protective coatings.
- MAG (MAG-10N) Pulsed Electroplating Power Supply offers CC and CV operating modes and pulsed (current and voltage) modes with precise control of frequency, time, and amplitude. The unit is intended for electrochemical deposition of metallic, alloy, and composite coatings, as well as surface modification processes.
- Kikusui PWR800H Programmable DC Power Supply (0–650 V, 0–4 A) operates in CC and CV modes. It is used to power and stabilise PEO/MAO and EPD processes, as well as other tasks requiring a stable high voltage/current source.
