微窝表面毛化已被证明是提高机械零件功能和性能的有效途径。穿透掩模电化学微加工(TMEMM)是一种常用的金属表面毛化加工技术，但在曲面毛化加工中仍具有很大的挑战性。本文提出了一种在圆柱体表面产生微窝阵列的TMEMM新工艺。在该TMEMM工艺中，引入了一种具有良好柔韧性和大量相互连接的微孔的泡沫金属薄膜作为阴极，并将其与可重复使用的穿透掩膜和工件集成在一起，形成三明治状组件。数值分析了被加工区域内的电流分布及其与通孔几何尺寸以及掩模中通孔相对位置的关系。采用这种TMEMM工艺，只需一次加工，就可以在平面和整个360°圆柱体表面产生大量几何尺寸均匀的微凹，凹陷深度和直径的最小变异系数分别为5.6%和2.4%。从理论上解释了这一有利结果的原因。本文提出的TMEMM工艺在高效、低成本地生成曲面上几何一致的表面纹理方面具有很大的潜力。
Surface texturing with micro-dimples has been proved to be an effective approach in many fields to improve the functionalities and performances of some mechanical components. Through-mask electrochemical micromachining (TMEMM) is a popular technique to create textures on metallic surface, but it is still very challenging to be used to texture curved surface. In this paper, a novel TMEMM process was proposed to generate micro-dimple array on the cylindrical surface. In this TMEMM process, a foamed metal film with a good pliancy performance and a huge number of interconnected micropores is introduced to serve as the cathode, which is further integrated with the reusable through-mask and workpiece to form a sandwich-like assembly. The current distribution within each region being machined and its correlation with the geometric dimensions of through-hole, as well as with the relative location of the through-hole in the mask, are analyzed numerically. With this TMEMM process, a great number of micro-dimples with a good uniformity in their geometric dimensions can be produced both on the planar and the entire 360° cylindrical workpiece surfaces in only one operation, showing the minimum coefficient of variation of the dimple’s depth and diameter being 5.6 and 2.4%, respectively. The reasons for such a favorable result are interpreted theoretically. The proposed TMEMM process here could have a great potential in generating geometrically consistent surface textures on the curved surface efficiently and low-costly.
