Multiple nanoscale parallel grooves formed on Si3N4/TiC ceramic by femtosecond pulsed laser

- Femtosecond pulsed laser nanotexturing of Si3N4/TiC ceramic was investigated.
- The optimum processing parameters for the formation of ripples were identified.
- Surface morphology, ablation dimension and surface roughness were measured.
- Formation mechanism of ripples on Si3N4/TiC ceramic surface was discussed.
