    摘要: A tool (1) for mechanochemical treatment comprises a shaft (10), a number n of working ledges (20), n≥1, and a force application arrangement (2). The force application arrangement (2) is configured for applying a working force (F) on the working ledges (20). The working ledges (20) comprises wear-resistant material with a Vickers number above 800 HV and a Young modulus above 200 GPa. Each working ledge (20) has a contact surface (22) facing away from a main axis (11) and having a surface roughness Ra below I μm. The contact surface (22) has a convex curvature which has a radius of curvature that is at most equal to a closest distance from that point to the main axis. A width of the contact surface (22) is less than r/2n. The working force applied on each working ledge (20) is at least P−L−r/2n, where P=107 Pa and L is the contact surface length.
