| 摘要 |
<p>The invention concerns a method for generating nanostructures to obtain on a zone of a metal workpiece (10) a nanostructure layer with a specific thickness, characterised in that it comprises: a step which consists in shot peening on an impact point of the zone of the surface of the workpiece (10) to be treated, for a specific time interval, at a specific speed and under variable angles of incidence at the same impact point a specific quantity of perfectly spherical balls (22), having specific dimensions and being permanently re-used during the shot peening; repeating the preceding step by displacing the impact point so that the whole set of impact points covers the entire surface of the workpiece to be treated; a step which consists in treating by diffusion of chemical compounds in the nanostructure layer produced during the nanostructure generating step.</p> |
