Abstract

Temperature distribution was measured using experiments means and modelled by employing a computational method for CO₂ and fibre laser surface treatment of a Si₃N₄ engineering ceramic. The temperature of the CO₂ laser surface treatment was 42% lower in comparison with that of the fibre laser. Both the bulk and the surface temperatures for the finite element model (FEM) were higher for the fibre laser surface treatment in comparison with the CO₂ laser surface treatment. Not only the this was due to the difference in the wavelengths but also the laser-beam brightness of the two lasers during the laser-Si₃N₄ interaction. In addition, both the FEM and the experimental model enabled the prediction of additional process parameters for future development of the laser surface treatment process for engineering ceramics.
