“…Drawing inspiration from the coupling phenomena in biological system, the functional theory of biomimetics was applied to the metals to improve the mechanical properties of materials and increase the reliability of structural components, especially the thermal fatigue resistance on the surfaces of components in hot working [7][8][9] . For a long time, how to improve the thermal fatigue resistance of materials is always one of the great problems of concern to researchers throughout the world.…”

Some kinds of particular functions possessed by natural organisms are often formed by coupling up the multiple typical features on their body surfaces. Inspired by the coupling phenomenon in biological system, the medium carbon steel specimens with the coupling effect of non-smooth mechanical property and microstructural features were fabricated by laser processing. Thermal fatigue behavior of specimens with biomimetic coupling surface was investigated and compared. The results confirmed that such a biomimetic method has the beneficial effect on improving the thermal fatigue property of medium carbon steel specimens. The related mechanisms behind the biomimetic coupling effect for explaining the enhanced thermal fatigue resistance were discussed preliminarily.biomimetic coupling, medium carbon steel, thermal fatigue, non-smooth mechanical property, microstructural feature, laser processingIn biological system, some kinds of functional characteristics on the body surface of plants and animals are often resulted from the synergic action that combines multiple different factors associated with their surface functions. These factors include geometry, structure, chemical composition, bioelectricity, flexibility, liquid secretions, etc, of the body surface [1] . The effect that the performance of the organisms or their parts is strongly enhanced by synergy of different factors in a well combinated manner can be called the coupling effect. The biological coupling endows the body surface of living creatures with many excellent, even special functions. For example, the coupling effect of the configuration of pangolin claws and the non-smooth morphology of their claw scales, makes them have the exceptional ability to reduce the adhesion and frictional resistance of soil [2] ; through coupling of the protuberance-shape morphology with different structures as well as hydrophobic materials on the surfaces, lotus leaves have the amazing waterrepellent and self-cleaning functions [3] ; the outstanding abrasive-erosion-resistant characteristic possessed by the desert lizards, can be ascribed to the coupling effect of the scale-shape non-smooth morphology and the multilayer flexibility of their body surfaces [4] , as shown in Figure 1(a)-(c). Moreover, the remarkable fractureresistant function owned by organisms is reflected typically in the leaf vein structure of trees, as shown in Figure (d). This structure with the coupling effect of different microstructures and non-identical mechanical properties, between the rigid veins and the flexible mesophyll, makes the leaf more resistant to tearing and breaking by wind.

“…On the other hand, laser treatment notably results in modification of alloy microstructure and thus improves related properties [3,[10][11][12][13]. Our previous studies [3,10,11] reported the mechanical properties and wear resistance of generally used steels processed by laser.…”

In this work, the mechanical properties and microstructures of vermicular graphite cast iron processed by selective laser surface alloying with ultra-fine ZrO 2 ceramic particulates were investigated. A particulate-reinforced metal matrix composite coating with the thickness of *650 lm was fabricated by laser treatment on the sample surface. The particulates were uniformly distributed in the microstructure of the coating. The tensile strength and microhardness both increased with the particulate fraction, since more tensile load was transferred from the matrix to the reinforcement showing essential strengthening effect. The composite coating also sharply reduced the wear mass loss and thus improved the wear resistance.

“…There are many methods available for manufacturing these non-smooth biomimetic units, among which laser processing has been successfully used [10][11][12] and proved to be effective because of its advantages of exceedingly high degree of process flexibility and better control of the surface properties. Previous works in our research group found that the non-smooth biomimetic unit fabricated by laser has a considerable effect not only on resisting wear but also on preventing the thermal fatigue cracks in die steel application [13][14][15] interaction between laser beam and materials in laser processing is a thermal process that could produce a wide range of surface morphologies as a result of phase transformation, melting and/or evaporation of the irradiated material.…”
