AbstractThe eroded surface of 2205 duplex stainless steel after liquid-solid jet impingement can be divided into three regions according to the severity of erosion-corrosion damage. The erosion-corrosion behavior for different local eroded regions was investigated using surface profile and potentiostatic polarization measurements. The results show that the critical flow velocity of these three regions is 13 m/s, 11 m/s and 15 m/s, respectively. The region with a lower critical value is more sensitive to erosion-corrosion damage with the increase of jet flow velocity showing much higher erosion-corrosion damage. The combined effect of impact angle and impact velocity of solid particles is the main reason causing the difference of critical flow velocity for different local eroded regions.
