Application
This instrument is suitable for studying the local corrosion distribution characteristics of metal surfaces in the laboratory, as well as the mechanism study of the occurrence and development of local corrosion. It can be widely used to study metal non-uniform corrosion behavior.
Working principle
CST520 Multi-electrode Array electrochemical system consists of two parts: a multi-electrode interface and an electrochemical testing system. It can not only test the electrode potential and short-circuit current of any single electrode, but also measure the EIS and polarization curve, significantly enriching the evaluation methods of materials’ corrosion resistance.
The multi-electrode interface mainly consists of RS485 communication circuit, IO expansion circuit, 10×10 relay matrix circuit, MCU circuit, etc. It supports up to 100-channel array electrode switching, with switch rate of up to 100Hz.
The Electrochemical mapper can not only conduct array electrode testing, but also serve as an independent potentiostat/electrochemical workstation with all techniques for corrosion measurements, such as open circuit potential (OCP), polarization curve (Tafel), linear polarization (LPR), EIS, M-S curve, and electrochemical noise (ECN) etc.
Potential and current scanning
The CST520 can achieve cyclic potential/ current scan of the surface, or potential/current vs. time scan of any single electrode, with real-time potential/current distribution display. The data can be imported into Origin to display the 3D graphs.
As shown in above picture, it shows the potential/current distribution. It can be seen that there are three areas with more negative potentials. Negative current also appears at the same areas in the current distribution diagram. Negative current means anode current, indicating that more severe corrosion occurs in these three areas on the electrode surface.
