Abstract  The laser surface texturing on the SiC mechanical seal samples were studied by using a Qswitched diodepumped Nd:YAG laser and the laser processing technique called “single pulse at a time, repeated at intervals”, and the geometric parameters of texture were measured by means of WykoNT1100 surface profiler, further the effect of laser processing parameters (pumping current, repetition frequency, number of excitations, scanning speed) on the geometrical parameters and quality of microtextures was analyzed. The results show that pumping current and number of excitations have an evident influence on the micropore processing quality, and repetition frequency is relatively small. However,pumping current, scanning speed and repetition frequency can greatly affect microgroove processing quality. High quality microtextures can be obtained via optimizing the laser processing parameters. For processing microdimple, the optimal laser parameters, such as pumping current and number of excitations are 14-16 A, 1-10, for processing microgroove. However, the optimal pumping current, repetition frequency and scanning speed are 14-16 A, 1 500-2 500 Hz and 8-25 mm/s, respectively.
