Abstract
In this work, the cavitation erosion-corrosion performances of X65 pipeline steel at different locations of Venturi pipe is studied. Results show that the collapse of bubbles at throat downstream would induce pitting damage, thus accelerating the localized corrosion. The cavitation erosion is totally induced by the corrosion enhanced erosion at the employed flow rate. The local hardness degradation and crack initiation at the anodic sites are the two basic requirements for the occurrence of erosion. Along with the formation of deep pits, the fracture of steel substrate at pit boundary becomes the main contributor of erosion, which is induced by the repeated bubble collapse and the assistant of corrosion. The synergy of corrosion and cavitation erosion is the main lead of steel failure in Venturi pipe.
