Micro Surface Texturing of Alumina Ceramic with Nanosecond Laser
چکیده انگلیسی

In order to fabricate micro surface textures on alumina ceramic, the effects of single pulse intervals processing and ring cutting processing on the laser surface textures were discussed. The advantages and disadvantages between the two kinds of processing method were compared. The crater diameter and depth increase with the increase of laser pulse energy, and the increasing number of pulses significantly affects the crater depth for the single pulse intervals processing. As for the ring cutting processing method, micro-pit depth changes with the average power, whereas the micro-pit diameter mainly changes with scan radium. By optimizing laser processing parameters the micro-pit dimensions could be independently controlled. These two methods could process micro-pits with different diameters and depth on alumina ceramic.
