“…Incorporating bionic textures on these tools can effectively reduce drilling forces, optimize stress distribution, and mitigate stress concentration issues, ultimately enhancing the quality of pre-drilling procedures [263]. A promising method involves integrating harmless solid lubricants into the bionic texture of medical tools to improve cutting execution and ease patient pain [42]. For instance, Liu et al [60] explored bionic designs inspired by the hydrophilic microstructure of Nepenthes openings to develop self-lubricating electrosurgical scalpels.…”

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.

“…The bionic PDC rock cutter has outstanding anti-wear properties with significant improvements in service life and drilling efficiency [11]. LU et al [12] designed four scalpels with different microserrations edges by mimicking the micro-serrations structure of the manzanita blade. Compared to standard commercial scalpels, the bionic scalpel produced stress concentration, reduced cutting forces, and reduced tissue damage due to its sharp serrated shape.…”

Along with the transformation and upgrading of the manufacturing industry and the arrival of the industrial revolution, the structure of parts is becoming more and more complex, the variety of materials, the demand for cutting performance of tools is increasingly diversified, and the design and development of tools are facing many challenges. By studying the cutting phenomena in nature, scholars have discovered that the teeth and claws, etc., of living organisms have unique structural characteristics, the design and development of tools that mimic the structural features of living organisms have become a new research direction. In order to solve the problem of high energy consumption in the cutting process and to reduce the resistance of the cutting process, five bionic cutting tools were designed based on preparation and geometric feature extraction of limpet teeth and applying them to the design of the tool structure, using the cutting force as the cutting performance index, and exploring the cutting performance of the bionic tools by comparing them with ordinary tools. The cutting force analysis revealed that the No. 2 bionic tool had a significant force-saving effect, with a 16.2% reduction in cutting force. The effect of cutting parameters on the No. 2 bionic tool was investigated through single-factor experiments. The results show that a limpet bionic cutting tool with appropriate dimensional parameters has a significant force-saving effect and improves the tool's cutting performance.

The failure of grey cast iron drum brake is mainly caused by thermal fatigue crack running through the top along the axial direction, which has the characteristics of regional failure. By using the advantages of laser fabrication technology, the single models with five different angles combined with the anti-crack ring were designed. The optical microscope, scanning electron microscope and X-ray diffraction were used to characterize the microstructure and phase of the drum brake material grey cast iron and the bionic coupling unit. Both single models and double combination models were tested for thermal fatigue and wear after thermal fatigue, respectively. The effects of angle on the thermal fatigue and wear resistance of the bionic coupling models were investigated. Experimental results show that the microstructure of the unit was better than that of the base grey cast iron due to the appearance of ledeburite, martensite and residual austenite after laser treatment. Besides, thermal fatigue crack has a great influence on wear performance. The thermal fatigue crack and wear loss weight are the least in the model with anti-crack ring + 45°angle, the main crack length is the shortest. The service life of the drum brake with the double combination bionic coupling model is increased by 50% compared with that of the untreated drum brake in bench test.
