Abstract


Laser micromachining of TiB2-based composite materials is extensively studied for its ability to produce precise and clean cuts without inducing deformations or cracks, vital for various industrial and military applications. This paper analyzes a nanostructured TiB2 ceramic obtained through microwave hybrid sintering, with a microhardness around 15 GPa. Laser micromachining is necessary to create cavities or complex internal structures in the TiB2 sample for sensor integration in defense applications. The primary objective of this research is to monitor the behavior of TiB2 during the laser cutting process, emphasizing the maintenance of structural integrity and the improvement of processing efficiency. The results will contribute to the optimization of laser applications for advanced processing of TiB2 nanoceramics.
