Abstract

The anti-wear ability of material surfaces is a hotspot of tribology research. Recently, it has been shown in bionics studies that the high anti-wear ability of some living creatures’ surface is related to their non-smoothness morphology. Such as pangolin; they live in soil and stone conditions, but they cannot be damaged by soil and stone at any time. This kind of bionic non-smoothness includes several morphology, such as squama, convex, concave and ripple shapes. In order to improve the anti-wear ability of roll, the bionic nonsmoothness technology was employed. Four kinds of roll samples with different surface morphology, such as squama, convex, concave, ripple, were made by laser texturing technology. The metallurgical structures of the samples wer
