Corrosion is a process involving deterioration or degradation of materials that results in huge economical losses. As corrosion processes are electrochemical in nature and involve two or more reactions, electrochemical techniques using sophisticated instruments are required to study them.
The Autolab instruments along with the NOVA software offer the corrosion practitioners a wide array of tools for studying these processes.
- FRA32M: Corrosion testing and research.
- ECN: Characterisation of coatings.
- Multi 4: Sequential measurements on up to 64 cells.
- pX1000: Critical pitting temperature measurements.
- EQCM: Determination of mass change.
- Reference and counter electrodes.
- Corrosion cell.
- Flat cell.
- Normal cells.
- Faraday cage.
- Rotating disc electrode (RDE).
- Linear sweep voltammetry: Identification of corrosion processes.
- Chrono methods: Identification of pit initiation.
- Electrochemical impedance spectroscopy: Detection of coating failure and identification of corrosion mechanisms.
- Tafel slope analysis: Automatic calculation of kinetic rate constants.
- Corrosion rate analysis: Automatic calculation of polarisation resistance and corrosion currents and rates.
- Fit and Simulation: Fitting of complex equivalent circuits.
- Multi-sine technique for quick low-frequency measurements.
