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