Laser surface texturing (LST) of silicon carbide (SiC) with the diamond coating (D/T-SiC) was studied in order to reduce friction and wear. The microstructure, morphology, and tribological properties of SiC substrate, textured SiC (T-SiC), and non-textured SiC with diamond coating (D/SiC) were also investigated for comparison. The samples modified by laser surface textured or fabricated with diamond coating (T-SiC, D/SiC, D/T-SiC) showed a conspicuous impact on reducing the friction and wear in dry friction, compared to SiC at various applied loads (5 N, 15 N, and 25 N). Additionally, the D/T-SiC showed lower friction coefficient and wear rate at all the conditions, especially, D/T-SiC reduced the friction coefficient of 79.7%, 84.8% and 86.2% compared to SiC, respectively, at applied loads of 5 N, 15 N and 25 N. The cylindrical textures were found to further reduce the friction coefficient by capturing abrasive, which decrease the width and depth of scratch of diamond coating. Furthermore, the diamond coating could decrease the deformation of cylindrical textures. Besides, a small amount of transition from diamond to sp2C at the counterface improved tribological properties. This work provides valuable guidance for SiC modification.
