| Abstract: |
| The surface texture has shown good effects in terms of improving the wear resistance of the parts, the friction reduction of the interface contact, the drag reduction of the material surface, and the enhancement or reduction of the material adsorption. According to the different surface functions, the design, processing and application of various bionic textures were reviewed from the aspects of wear-resisting surface, drag-reducing surface, hydrophobic surface and adhesive (desorption) surface. The study found that the size of the wear-resistant bionic texture pattern is relatively large, mostly above 20 µm, and the stable structure can withstand large external forces; the drag reduction and hydrophobic surfaces have a fine protrusion-like structure, which can effectively change the mechanical properties of the surface through the microstructure; and the adhesive surface benefits from the shape and size of the microstructure of the organism, and the hairy microstructure has good adsorption. In the processing method, laser etching can accurately control the processing size and geometric shape, and chemical etching can obtain a finer surface shape. Good results have been achieved in applications such as mechanical seals, piston rings, cutters, sliding bearings and gears. However, up to now, the research on surface bionic texture is still complicated and no system has been formed. The relevant design and mechanism of action are not perfect. By analyzing the functional design of bionic texture patterns, multi-scale composite processing and the impact on the service performance of parts, this paper aims to provide ideas and more scientific design methods for the design of bionic texture patterns, and find the processing technology suitable for each functional surface. The bionics is applied to texture technology, borrowing fine functional properties from organism, in order to be more widely used in engineering. |
