As a popular surface modification technology for improving tribological performance in recent years, surface textures have been widely studied by research groups and have been applied to different friction units to reduce friction and wear. With the development of advanced manufacturing technology, it is possible to fabricate surface texture of complex shape and small dimension efficiently and economically. At the same time, study on design of surface textures is transferred from experimental trial and error method to theoretical optimization. The development of surface texturing design and its tribological application in recent years is discussed. Firstly, the manufacturing of concave/convex textures and the lubrication characters of concave textures in various lubrication regimes are introduced. Then, the development of hydrodynamic lubrication and mixed lubrication model is discussed. Meanwhile, typical regular shapes and irregular shapes on the tribological behaviors of surface texturing are summarized. Followed by is the summarization of recent studies on the selection and optimization of the dimension of circular dimples for various materials and under different operating conditions. Effects of the distribution/layout of circular dimples are mainly discussed by taking several typical researches as examples. For specific friction pairs, such as bearings, corresponding texture distribution/layout design are also introduced in this overview. Lastly, this overview summarizes the limitations of surface texturing design in available literature and gives the prospect in future.
