METHOD FOR A MECHANICAL TREATMENT OF A METALLIC SURFACE

摘要

The invention pertains to a method for a mechanical treatment of a surface (7) of a metallic substrate (6) of an article of manufacture (1) comprising the step of treating the surface (7) with abrasive particles (5), which particles (5) comprise a metallic nitride, in particular aluminium nitride (A1N), titan nitride (TiN), and/or silicon nitride (Si3N4), in particular a sintered silicon nitride (SSN). The abrasive particles (5), preferably have on average a fracture toughness of between 5.5 MPa*m<1/2> and 10.0 MPa.*M<1/2>.
