Effects of 3D printed surface texture on erosive wear

Additive Manufacturing (AM), which more commonly known as 3D printing, is an extremely popular, fast and flexible manufacturing method. Rectangular prismatic textures are created on a surface via 3D printing technique. It is observed that the surface texture obtained by AM reduces particle erosion by half under the same erosion direction, and the angle of blasting direction on the prepared surface texture has a major effect, where there is an evident change in wear rate when the surface texture is smaller than the particle size. Also, it is seen that small changes in the dimension of the texture has no remarkable effect on particle erosion.
