Abstract

The first and second law efficiencies of laser treatment of alumina surface are examined in line with the same laser scanning speeds and laser power levels used in the experiments. Temperature and stress fields developed in the laser-treated region are predicted for two laser power levels using the ABAQUS code. The microstructural changes in the laser-treated region are investigated using scanning electron microscopy and x-ray diffraction. It is found that the first and second law efficiencies reduce with increasing laser output power. von Mises stress attains high values at high laser power settings and is more pronounced at high laser scanning speeds.
