Insight into Corrosion Phenomena

Corrosion is a process involving the 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 offer corrosion practitioners a wide array of tools for studying these processes.

Modules

• FRA32M – Corrosion testing and research

• ECN – Characterisation of coatings

• MUX.Multi 4 – Sequential measurements on up to 64 cells

• pX1000 – Critical pitting temperature measurements

• EQCM – Determination of mass change.

The Autolab comes with an assortment of accessories such as reference and counter electrodes. It also features a number of software methods including the linear sweep voltammetry, chrono methods and electrochemical impedance spectroscopy. It can also accomplish many analyses including the Tafel slope analysis, corrosion rate analysis, and fit and simulation.

The Autolab features:

  •  A multi-sine technique for quick low frequency measurements
  •  Automatic determination of corrosion rate in NOVA software
  •  High compliance voltage of the PGSTAT100N allows corrosion measurements on cells with high ohmic drop
  • Galvanic coupling, electrochemical noise and zero resistance amperometry measurement
  • The analog and digital inputs/outputs allow the combination of electrochemical methods with other techniques
  •  The MUX module allows the automation of routine corrosion measurements by running up to 64 cells sequentially.
