Simulation and Experiment on Micro-Texture of Bionic Surface Array

Abstract

In view of the anti-friction and anti-adhesion characteristics of bionic surface structure in bioengineering, a new processing technology of hole-to-hole strip sprinkler tool is proposed innovatively to achieve precision and large-scale surface micro-texture manufacturing. On the basis of electrolytic jet mask processing, the array structure of strip nozzle with variable hole spacing was designed. Combining with electric field parameters, the model was established by COMSOL Multiphysics software and the simulation analysis was carried out. Experiments show that the technology has high processing efficiency, low surface roughness, regular morphology and good consistency of the fabricated arrays, which provides a new idea for the fabrication of bionic micro-texture arrays.

“…Furthermore, the microtexture possesses the ability to store lubricants to provide secondary lubrication in the oil lubrication situation. In addition, the hydrodynamic lubrication effects are formed during relative motion, minimizing material wear and enhancing component service performance (Chen et al , 2020; Shimizu et al , 2020; Jiao et al , 2023).…”
