Abstract
We present here a study of marking of thermoplastic polymers by thermal ablation, produced by an infrared laser source. This marking allows to improve the tribological behaviour of polymers in specific applications.The experimental part of the study has been performed using a CO2 laser source and a polycarbonate polymer. A model of energy exchange was developed in order to estimate the depth, the width and the shape of this marked surface.Furthermore, we present an experimental validation of our numerical results. We show that this simulation allows to have a good evaluation of the dimensions of the branding of our polymeric samples. Then, we present the limitations of the model and the ways to follow to improve it.We present here a study of marking of thermoplastic polymers by thermal ablation, produced by an infrared laser source.
