- Abstract:

Aiming at the characteristics of liquid-solid motion and corrosion process of liquid-solid two-phase flow system, it is pointed out that the interaction between erosion and corrosion is the main factor for erosion corrosion failure of materials. Based on the interaction mechanism, the relevant mechanisms and models of flow-induced erosion and corrosion in liquid-solid two-phase flow are discussed, the importance of fluid mechanics in the erosion corrosion process is discussed, and the mutual promotion of flow and corrosion process is analyzed. Since different environmental media and materials have different corrosion mechanisms, the range of action of erosion and corrosion can be judged by the ratio of the two components of corrosion loss and erosion weight loss in erosion corrosion, so as to provide certain guidance for material selection and anti-corrosion design.
