Surface-texturing is a useful method of modifying surface frictional performance. A simple,novel, easily-controlled method was used to fabricate different kinds of textures on an Ni-Cocoating surface. The nanotribological properties were characterised by atomic force microscope(AFM) with a colloidal probe. The results showed that, compared to the original Ni-Co coatingsurface, the nanotextured surface can adjust the surface friction forces. The half-elliptic patternshave better tribological properties than hemispherical patterns. Therefore, both laser energy andlaser scanning speed will influence the friction performances of Ni-Co coating surfaces.
