Abstract

Purpose

This paper aims to enhance lubrication performance of the pitcher plant–like textured surface with various parameters.

Design/methodology/approach

A pitcher plant–like structure surface is fabricated on the copper alloy, and the lubrication performance of the pitcher plant–like structure with various parameters is evaluated. In addition, the pressure distribution and oil film load capacity of the pitcher plant–like surface are simulated based on Navier–Stokes equations.

Findings

When the direction of motion aligns with the pitcher plant–like structure, the friction coefficient remains lower than that of the nontextured surface, and it exhibits a decreasing trend with the increasing of the texture width and spacing distance; the lowest friction coefficient (0.04) is achieved with B = 0.3 mm, L = 1.0 mm and θ = 45°, marking a 75% reduction compared to the nontextured surface. Simulation results demonstrate that with the increase in texture width and spacing distance, the oil film load-bearing capacity demonstrates an increasing trend.

Originality/value

Bionic pitcher plants are prepared on the copper alloy to improve the lubrication performance and wear resistance.

不同参数下投手植物纹理表面的润滑性能研究

设计/方法/途径在铜合金上制作了一个类似于投手植物的结构表面，并评估了不同参数下类似于投手植物结构的润滑性能。此外，还根据纳维-斯托克斯方程模拟了类植物表面的压力分布和油膜承载能力。研究结果当运动方向与投手状植物结构对齐时，摩擦系数仍然低于无纹理表面，并且随着纹理宽度和间距的增加呈下降趋势；当 B = 0.3 mm、L = 1.0 mm 和 θ = 45° 时，摩擦系数最低（0.04），与无纹理表面相比降低了 75%。仿真结果表明，随着纹理宽度和间距的增加，油膜承载能力呈上升趋势。独创性/价值在铜合金上制备仿生投手植物，以改善润滑性能和耐磨性。同行评审本文的同行评审记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-04-2024-0119/。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
