<p>The invention concerns a method of making a satin finish surface on a part made of a material with a Vickers hardness greater than 1000 HV including at least one polished surface, mainly including the following steps: taking a support for the part and a pulse laser, capable of a relative movement with respect to each other in an XY plane, exposing the polished surface locally to a laser pulse with enough energy to cause local melting of the polished surface so as to form a micro-crater, repeating the laser pulses simultaneously with a relative movement of the piece relative to the laser, so as to traces micro-furrows on the polished surface, formed by the alignment of several successive partially overlapping micro-furrows, the micro-furrows being substantially parallel to each other and equidistant, and together defining the satin finish surface.</p> |
