摘要

铜锡合金具有优良的强度和耐腐蚀性，在工程和制造业中有着广泛的应用。然而，如何在深小盲孔中制备厚度均匀、化学成分均匀的Cu-Sn涂层是一个重大挑战。本文提出了一种带可变直径辅助阳极的摩擦辅助射流电沉积方法。通过验证的多物理场仿真，对变直径阳极的外形进行了优化。对制备的样品进行了射流电沉积和摩擦辅助射流电沉积实验。表征结果表明，FJED制备的涂层厚度均匀，化学成分均匀。通过去除氢泡，提高了材料的硬度和附着力。所有涂层均表现出优异的耐腐蚀性。结果表明，变直径阳极提高了涂层的均匀性，摩擦刷提高了涂层的力学性能。

Friction assisted jet electrodeposition using variable diameter anode for enhanced uniformity of Cu-Sn coating in deep small holes

Copper-tin alloys are critical due to the excellent strength, corrosion resistance, and wide range of applications in engineering and manufacturing. However, it was a significant challenge to fabricate Cu-Sn coatings with uniform thickness and chemical composition in deep small blind holes. In this paper, a friction assisted jet electrodeposition with a variable diameter auxiliary anode was proposed. The profile of variable diameter anode was optimized by the validated multiphysics simulation. Experiments of jet electrodeposition and friction assisted jet electrodeposition (FJED) were conducted to fabricated samples. Results of characterizations showed that coatings prepared by FJED had uniform thickness and chemical composition. The hardness and adhesion were enhanced by removing hydrogen bubbles. All coatings exhibited an excellent corrosion resistance. The mechanism of FJED was revealed that the variable diameter anode improved the uniformity of coatings, and frictional brush enhanced the mechanical properties of coatings.
