Abstract

Un metodo per colorare una superficie metallica (12). in particolare in acciaio inossidabile. comprende il sottoporre la superficie (12) all'azione di un fascio di luce laser (L) avente una determinata frequenza, potenza e per un tempo prefissato, tale azione comportando la presenza di una opportuna densità di energia o potenza laser sulla zona di superficie metallica (12) interessata dalla luce laser (L) tale da creare una conseguente colorazione di tale zona.Il metodo viene attuato mediante un dispositivo comprendente un generatore di luce laser (1), mezzi (3) per focalizzare il fascio laser (L) emesso su una superficie metallica (12) e mezzi (17; 23, 24) per variare la densità di energia che tale fascio (L) rilascia a tale superficie così da avere diverse sue colorazioni.
