METHOD OF APPLYING IMAGE ON PRECIOUS METAL PRODUCTS BY LASER ENGRAVING

摘要

FIELD: jewelry. ^ SUBSTANCE: invention relates to methods of applying images on precious metal products by laser engraving. Method includes polishing product surface, itsrefinement, product fixation and further application of image on product by beam of laser irradiator, in whose program block computer image was preliminarily transferred. Surface polishing and refinement are performed until 9-class surface roughness is achieved. Before product fixation its surface is moistened with silicon-organic polyethylsiloxane liquid. Image is applied by point melting of surface with laser beam to 14-class roughness of product surface. Before image application product surface is covered with rhodium. ^ EFFECT: giving image contour three-dimensional effect. ^ 2 cl, 1 dwg
