Title:
METHOD FOR GENERATING IRIDESCENCE ON METALLIC SURFACES
Document Type and Number:
WIPO Patent Application WO2003106099
Kind Code:
A3
Abstract:
The present invention is a method for generating iridescence on metallic surfaces characterised in that it comprises the use of a biased laser beam (2) which is made incident onto a metallic target surface (3) so that a preset area of said surface is swept or passed by said laser beam with a preset speed and according to a preset path so that the given energy per impacted surface unit is enough to produce a surface material melting with a very limited depth.
