Abstract: Herein, we utilized an innovative pathway to obtain exceptional resistance to the cavitation erosion-corrosion behaviour by combining surface texturing with severe-surface deformation. Severe-surface deformation was carried out using stationary friction process (SFP) followed by micro-texturing through a micro-imprinting approach. The textured sample after processing (SFP+T) showed 6-7 times high erosion resistance compared to As cast sample under ultrasonic cavitation conditions. In addition, the SFP+T sample were able to sustain the similar trend in erosion-corrosion medium as well. Furthermore, the flow field characteristic of textured and non-textured samples was investigated using numerical calculations in ANSYS-Fluent. The remarkable improvement in erosion-corrosion resistance was attributed to the finer grain and fluid flow distribution in the textured surface.
