发明名称 METHOD FOR MARKING THE SURFACE OF A MECHANICAL PART WITH A PREDEFINED GRAPHICAL REPRESENTATION HAVING A HOLOGRAPHIC EFFECT
摘要 A method of marking the surface of a mechanical part with a predefined graphic having a holographic type effect, the method including using a laser source to apply a succession of laser pulses to the outside surface of a part for marking, with different masks being interposed between the laser source and the outside surface of the part, each mask having a particular pattern, each laser pulse having a power density of at least 20 MW/cm2 and a duration that is less than or equal to 100 ns.
