| 摘要 |
<p>The invention relates to a process for the surface treatment of a metal part, in which a surface of the metal part (1) is exposed to a stream of substantially spherical particles, in such a way that every portion of the surface receives the particles according to multiple primary incidences, the primary incidences of the particles on one portion of the surface being distributed essentially in the form of a cone or a conical film having an apex half-angle of between 10° and 45°, until a nanostructured surface layer (3) is obtained, said layer having a mean thickness of greater than 50 µm. The particles have a diameter of less than 2 mm and greater than 0.1 mm and are projected at a speed of between 40 m/s and 100 m/s.</p> |
