Surface Texturing on Polycrystalline Diamond Compact Cutter by Nanosecond Laser Processing

In this article, a method for preparing surface texture of polycrystalline diamond compact (PDC) cutter based on nanosecond laser direct is reported. The relationship between the structure of the surface texture with the laser power, scanning speed, and processing cycle of the nanosecond laser is systematically investigated. By changing the laser power, scanning speed, and the number of processing cycle, different nanosecond laser energies are obtained for processing PDC cutter, and the nanosecond laser parameters are precisely changed to achieve the purpose of laser modification and ablation. By controlling the parameters of nanosecond laser processing, micrometer-scale surface texture on PDC cutter are realized. The surface morphology of the resulting preparation is analyzed. This study provids an experimental basis for the utilization of laser surface texturing technology to improve the performance of PDC cutter, and promotes the further research and development of drilling and machining tools.
