摘要	The impingement angle has a significant influence on the slurry erosion behavior. There is limited knowledge of the effect of the impingement angle on the erosion of the micro-structured surface. Slurry erosion experiments were carried out on the V-shape grooved surface at four different impingement angles (30 degrees, 45 degrees, 60 degrees, and 90 degrees) in the slurry with 5.1 m s-1 velocity and 5 wt% sand content. Mass loss measurement, surface micro-morphology, roughness test, and nanoindentation revealed the relationship between microstructure damage and impingement angle. The effects of the area and impingement angle on erosion were discussed. The results show that the slurry erosion of the V-shape grooved surface displays a similar trend with the impingement angle to the smooth surface but with a relatively low erosion degree. The slurry erosion is alleviated to the most at the impingement angle of 45 degrees. The ratio of the top surface to the grooved surface and the actual impingement angle to the grooved surface play essential roles in reducing the slurry erosions. This work can help to design the surface microstructure and set the relative position of the impingent flow to the target material surface.
