Laser-Structured Components Made of SiC, Si₃N₄, Al₂O₃ or ZrO₂
The advantages of ceramics in the tribological environment are well known. In order to make bearing systems even more robust, structures from classic minimum lubrication systems are now also being transferred to ceramic components. We apply this to our proven materials such as: SiC, Si3N4, Al₂O3 and ZrO₂. These structures are introduced by laser and are freely programmable, taking into account the beam radius of the laser. Through the combination of the optimized laser process and the adapted material properties, we have succeeded in significantly increasing the sharpness of the edges and, despite thermal shock from the laser, in depicting the edges without cracks. The geometry shown is without any reference and is intended to show the possibilities.
