Abstract

Bronze coatings are widely used across various industries due to their excellent properties. However, achieving uniform composition and thickness, adopting environmentally friendly technologies, and enhancing manufacturing efficiency remain significant challenges. In this study, a multiphysics model was developed by coupling convection, cation transport, and electrochemical reactions to simulate jet electrodeposition in small-diameter holes. The influence of anode design and cation concentration on the chemical composition and thickness of bronze coatings was investigated via a combination of simulation and experimental validation. By analyzing the interactions among convection, diffusion, and electromigration, the mechanism of jet electrodeposition was elucidated. The results showed strong agreement between simulations and experiments, confirming that the jet electrolyte effectively disrupts the diffusion layer, thereby sustaining the reaction on the cathode surface. This work provides valuable insights into optimizing jet electrodeposition for the fabrication of high-quality bronze coatings in deep small holes.

深小孔喷射电沉积青铜涂层均匀性的多物理场模拟与实验研究

青铜涂料因其优异的性能被广泛应用于各个行业。然而，实现均匀的成分和厚度、采用环保技术以及提高制造效率仍然是重大挑战。在本研究中，建立了一个耦合对流、阳离子输运和电化学反应的多物理场模型来模拟小直径孔中的射流电沉积。通过模拟和实验验证相结合的方法，研究了阳极设计和阳离子浓度对青铜镀层化学成分和厚度的影响。通过对对流、扩散和电迁移相互作用的分析，阐明了射流电沉积的机理。模拟结果与实验结果非常吻合，证实了射流电解质有效地破坏了扩散层，从而维持了阴极表面的反应。这项工作为优化深小孔中高质量青铜涂层的射流电沉积提供了有价值的见解。
