Abstract: This work investigates friction and wear properties of non-smooth surface material, on which many concaves and striae called non-smooth units distributed regularly. These units are designed by imitating the body surface morphology of some biology and manufactured by laser. Result shows that wear resistance of cast-iron material with bionic non-smooth surface was increased more than one times compared to material with smooth surface, and friction coefficient was increased by 66% or more. Furthermore, wear resistance and friction coefficient of material have a close relationship with hardness, size of unit and space between units. Improvement of friction and wear performance was attributed to the fact that there are numerous strengthened local areas produced on the bionic non-smooth surface and it enhanced the rough surface and withstood the wear.
