Paper Abstract

On the last recent years many new Laser Surface Processes have been studied and tested in the field of the L.M. &mgr;W. - Laser Material Micro Working. Still today many of these "young" processes are to study and more and more searches are dedicated to they. These are the Marking, Texturing, Fine Texturing, Filling, Polishing, Micro Shot-Penning, Silking and Colouring. This experimental work reports the results obtained in the field of the Laser Surface Fine Texturing on AISI 304 and 430 Stainless Steels by using a Marking System, that is a Nd:YAG Laser, VECTORMARK type by TRUMPH ( D ). So some new laser surface finishes, called by Authors, - Effetto tessuto, con trama e ordito (Woven effect, with weft and warp) - Effetto pelle scamosciata ( Effect shammy leather ) - Effetto pelle uncinata ( Effect hooked skin ) - Effetto pelle unghiata ( Effect skin looking like scratch ) - Effetto pelle damascata ( Effect damask skin ) - Effetto speculare , ottonato ( Specular effect, looking like brass ) Effetto speculare, bronzato ( specular effect looking like bronze ) - Effetto speculare, argenteo ( specular, looking like silver effect ) - Effetto speculare, ramato ( Specular effect, looking like copper ), Effetto Speculare, dorato ( Specular effect, looking like gold ) - Effetto speculare , dorato, a raggiera ( Specular effect, looking like gold, to aureole) , were carried out. The work is still in progress.
