Method of decorating glass and ceramic articles

摘要

Decorative processing is performed with repetitively pulsed discharge at atmospheric pressure of a (RP TEA) by CO2 laser with pulse energy 1 to 5J, power density at operation from 1x106W/cm2 to 6x107W/cm2, pulse duration from 50 to 100 ns and average power 1 to 1000W whereby the mated area with one shot is from 0.5 to 2 cm2. The apparatus has a base with an upright on which are fastened parallel elements and a screw that is seated in its upper end in a thrust element and at its lower end is linked by an articulation to an electric motor. The screw drives a fork guided on the parallel elements. A slide is fastened to the fork and has longitudinal channels and a plate for inclination at increments of 15 DEG . To this slide is fastened a second electric motor and on its axis is mounted a carrier on which is fastened a mask in which is fixed the article to be decorated. On the rotating bearer a disk can be fastened on which are mounted four spokes with four springs and a repleceable stand.
