**1. Introduction**

Every year, erosion-corrosion causes severe damage in slurry transportation and related industries [1]. Many groups from the industry and universities have spent a lot of effort to understand this phenomenon and ways to prevent or reduce its effects. In erosion-corrosion, there are three separate phenomena: impact of solid particles (on the surface of the material), electrochemical reactions, and fluidity of the medium. These processes interact with each other and create erosive corrosion, forming a completely complex phenomenon. **Figure 1** shows the interaction between erosion, corrosion, and the fluid environment. This shows that the erosive corrosion process can only exist if erosion, corrosion, and the fluid environment exist at the same time.
