AI Technical Summary
Existing methods for studying temperature difference corrosion mostly involve measuring corrosion between non-connected metal samples in a dual solvent bath. These methods cannot accurately reflect the temperature difference corrosion situation of different parts of the same metal in reality, and traditional methods differ significantly from actual working conditions.
The same metal sample was used to encapsulate both ends to construct a conductive high-temperature and low-temperature measurement terminal. A salt bridge was used to shorten the distance, and a connected temperature difference corrosion three-electrode circuit was constructed by combining a semiconductor heating element and a temperature control device. The measurement was performed through an electrochemical workstation.
It enables controllable measurement of temperature difference corrosion in different regions of the same metal, which is closer to the actual corrosion situation and promotes the improvement of the knowledge system in the field of temperature difference corrosion and the accurate prediction of corrosion laws.
