Abstract

The surfaces of two engineering ceramics, LT35 (TiC + Al2O3) and Si3N4were irradiated with a high power KrF Excimer laser. The effect of laser pulse frequency, energy intensity and number of pulses upon the surface morphologies and roughness were examined. Conical structures on the treated surfaces were observed after the laser treatment. The ablation depths were found to be dependent upon the type of ceramics and laser processing parameters. The treated surfaces were adhesion bonded using a toughened epoxy resin adhesive. Significant improvement in adhesion shear strength of the bonded specimen with laser-treated surfaces were achieved as compared with those specimen with surfaces in the as-received, SiC-paper-abraded and sand-blasted conditions.
