Corrosion Mechanism and Influencing Factors of Metal Materials in Carbon Dioxide Reactor
This paper analyzes the impact mechanism of carbon dioxide medium on metal corrosion,assessing the impact of temperature pressure and the nature of material properties on the corrosion rate,and proposing effective protection countermeasures such as coating construction,alloy design and surface treatment.Studies have found that carbon dioxide can promote metal electrochemical and gas phase corrosion;the degree of corrosion is closely related to temperature,pressure and material stability;and the protection layer can effectively slow down the corrosion rate.Therefore,the correct understanding of the corrosion mechanism and adopting targeted protection measures can significantly improve the metal corrosion resistance and ensure the long-term stable operation of the related device.
