Current density potential curve
The current density potential curve is an important tool in galvanic corrosion testing and is used to characterize the electrochemical reactions at an electrode. This curve shows the relationship between the applied voltage and the resulting current density at the electrode surface.
In galvanic corrosion tests, the current density potential curve is used to analyze the corrosion behavior of a metal in contact with another metal or an electrolyte solution. By varying the voltage, the current density is measured, which provides information about the reaction kinetics and the corrosion tendency of the system.
The interpretation of the current density potential curve enables the determination of various parameters such as the corrosion potential, the corrosion current and the Tafel slope. These parameters provide important information about the corrosion resistance and the behavior of the material in different environments.
The current density potential curve is therefore a crucial tool for evaluating and understanding the corrosion resistance of materials and is used in many areas, from materials testing to the development of corrosion-resistant alloys.
