... blades, etc.) also suffer from erosion ( Ref 44 – 46 ). Erosion occurs as the result of several different mechanisms, depending on the composition, size, and shape of the eroding particles; their velocity and angle of impact; and composition and properties of the surface material being eroded...

... the line-of-sight process, and internal and external coating is possible. Substrate geometries with sharp edges and undercuts should be avoided, and particle impact angle should be preferably perpendicular to the surface, if the different tolerances allow for it. The surface of the workpiece must...

..., the scattering angles of incoming particles within a certain range of small impact parameters (<0.1 Å) are large enough to prevent them from penetrating the region immediately behind the atom. The region behind the atom that the incoming particles cannot penetrate is called a shadow cone. An area free...
