Abstract

In this work, the technical aspects of laser marking using organometallic films of different compositions are reported. Orasols of different types and palladium (II) acetate are used, for the first time, to produce permanent markings of various colors on different substrates. Ceramic and plastic substrates were used. The deposition process is a photothermal process and the markings were carried out using an argon ion laser operating at λ = 514 nm. Two laser marking techniques are used with the orasol dyes and palladium (II) acetate. The first of these two techniques is mask marking, where laser light is projected onto a workpiece through a mask replicating the information to be marked. The second technique applied is real-time motion marking. The workpiece was translated under the stationary laser beam using a programmable stage translator. For both techniques, optimum marking parameters (scanning speed/exposure time, power, and deposited line width) are reported along with typical examples.
