Abstract	The application of rolling for fabricating grate on titanium stripe has been explored in this paper. Then the mechanically robust Ti(C,N) diffusion layer was synthetized directly on the grates by laser carbonitriding in the mixture gas of nitrogen and methane. The results shows that the carbonitriding process is accelerated by temperature enhancement with decreasing scanning speed. The Ti(C,N) diffusion layer is kept at 2 μm in thickness, when the scanning speed is smaller than 4 mm/s. The contact angle increases from 20° to 143.6° by designing an appropriate grate size and surface roughness. Meanwhile, the relationship between hydrophobicity, hardness performance and scanning speed is also discussed. The hardness of diffusion layer increases with decreasing laser scanning speed, and is up to 11.2 GPa. The surface structure and hydrophobic state are maintained after three cycles of sandpaper abrasion, which has improved the robustness of surface grate.
