“…27 Inspired by the microstructure on the dung beetle head, the drill with bionic structure is invented. 28 Based on the principle of bionic tribology, the micro-texture surface with large volumes could capture more wear debris and lubricant, which led to a longer wear life and better tribological properties. Hydrodynamic lubricating oil film could be formed on the biomimetic surface with micro-structure under lubrication condition.…”

With an increase in extreme and complex work conditions in the fields of aircraft industry and high-speed train, single surface strengthening or single surface machining is not satisfactory with repeated requests of spherical plain bearings, which results in serious wear. Therefore, in this paper, a compound method of ultrasonic surface rolling process and surface texture was proposed on the basis of investigating the wear mechanism to meet the tribological property requirements of spherical plain bearings. The theoretical and experimental results show that low micro-hardness and low shear strength of surface material, rough surface, and poor lubrication are the important factors contributing to the wear of spherical plain bearings. The surface roughness Ra and Rz of processed spherical plain bearings are reduced to 0.02 mm and 0.14 mm from 0.35 mm and 2.1 mm, respectively, and the micro-hardness of surface material is increased by about 20%. The double-sine micro-textures with the width of 120 mm and the depth of 20 mm produced by laser machine, together with the circular groove, provide satisfactory lubrication for the spherical plain bearings. Finally, the wear resistance properties of spherical plain bearings were increased by more than 55%. The proposed synergistic methods have great advantages in improving the tribological properties of key fundamental components, especially for spherical plain bearings.

“…Effectively mitigating erosion wear depends on optimizing the interaction and interference between contributing factors such as geometry, material, and mechanics. For instance, inspired by the head and pronotum surface of the dung beetle, Yang et al and others [41,97,191] constructed and optimized a dung beetle-inspired textured drill bit surface, achieving better wear reduction and efficiency. However, the exact size and location of the dome and pit structures on the drill bit demand optimization based on soil environment and dung beetle species as the solid particles hitting these structures change trajectory, reducing wear on other structures.…”

Friction, wear, and the consequent energy dissipation pose significant challenges in systems with moving components, spanning various domains, including nanoelectromechanical systems (NEMS/MEMS) and bio-MEMS (microrobots), hip prostheses (biomaterials), offshore wind and hydro turbines, space vehicles, solar mirrors for photovoltaics, triboelectric generators, etc. Nature-inspired bionic surfaces offer valuable examples of effective texturing strategies, encompassing various geometric and topological approaches tailored to mitigate frictional effects and related functionalities in various scenarios. By employing biomimetic surface modifications, for example, roughness tailoring, multifunctionality of the system can be generated to efficiently reduce friction and wear, enhance load-bearing capacity, improve self-adaptiveness in different environments, improve chemical interactions, facilitate biological interactions, etc. However, the full potential of bioinspired texturing remains untapped due to the limited mechanistic understanding of functional aspects in tribological/biotribological settings. The current review extends to surface engineering and provides a comprehensive and critical assessment of bioinspired texturing that exhibits sustainable synergy between tribology and biology. The successful evolving examples from nature for surface/tribological solutions that can efficiently solve complex tribological problems in both dry and lubricated contact situations are comprehensively discussed. The review encompasses four major wear conditions: sliding, solid-particle erosion, machining or cutting, and impact (energy absorbing). Furthermore, it explores how topographies and their design parameters can provide tailored responses (multifunctionality) under specified tribological conditions. Additionally, an interdisciplinary perspective on the future potential of bioinspired materials and structures with enhanced wear resistance is presented.

“…e sealing performance of the high-pressure centrifugal pump can be improved by adding groove structures onto the joint mouth circumference [25]. e convex, pitted, and grooved structures of dung beetles, lizards, and shells are responsible for the high wear-resistance, resistance reduction, and sealing performance [26][27][28]. Earthworms are endowed by wavy nonsmooth surface structures with high resistance reduction and wear-resistance ability [29].…”

The mud pump piston is a key part for providing mud circulation, but its sealing performance often fails under complex working conditions, which shorten its service life. Inspired by the ring segment structure of earthworms, the bionic striped structure on surfaces of the mud pump piston (BW-160) was designed and machined, and the sealing performances of the bionic striped piston and the standard piston were tested on a sealing performance testing bench. It was found the bionic striped structure efficiently enhanced the sealing performance of the mud pump piston, while the stripe depth and the angle between the stripes and lateral of the piston both significantly affected the sealing performance. The structure with a stripe depth of 2 mm and angle of 90° showed the best sealing performance, which was 90.79% higher than the standard piston. The sealing mechanism showed the striped structure increased the breadth and area of contact sealing between the piston and the cylinder liner. Meanwhile, the striped structure significantly intercepted the early leaked liquid and led to the refluxing rotation of the leaked liquid at the striped structure, reducing the leakage rate.
