电解加工（ECM）是一种成熟的洗脱方法，具有加工速度快，适用于难加工材料，并且由于工件和刀具之间的非接触而减少了刀具磨损。然而，ECM难以精确加工和制备纳米结构。另一方面，短脉冲激光（SPL）可以制造称为LIPSS（激光诱导周期性表面结构）的精细周期性结构，据报道，LIPSS为材料提供了减少摩擦，改变润湿性和改善生物相容性等功能。然而，能够制造纳米结构的SPL对于创建大尺度形状是不稳定的。合适的加工方法取决于所需形状和结构的规模，并且在表面上创建形状和制造纳米结构的复杂过程需要长的加工时间。提出了SPL和ECM混合制造工艺（SPLECM）来有效地制造多尺度结构，SPL增加电场强度使ECM能够提高加工速度并在电化学加工表面上制造纳米结构。在这项研究中，与SPL和ECM的混合过程中的304不锈钢基板上的多尺度结构的制造的影响进行了实验研究。提出的方法能够提高加工速度和制造多尺度结构。这项研究证明了SPLECM在表面上同时创建形状和制造纳米结构的功效。
Electrochemical machining (ECM) is a well-established elution method with high processing speed, application to hard-to-cut material and less tool wear as noncontact between a workpiece and a tool. However, ECM is hard to process precisely and fabricate nanostructures. A short-pulsed laser (SPL), on the other hand, can fabricate fine periodic structures called as LIPSS (laser-induced periodic surface structures), which has been reported to provide materials with functionalities such as the reduction of friction, the change of wettability and the improvement of biocompatibility. Nevertheless, an SPL capable of fabricating nanostructures is unstable for the creation of large scale shapes. The appropriate processing method depends on the scale of the demanded shape and structure, and it takes long processing time with the complicated process to create the shape and fabricate nanostructures on the surface. The hybrid manufacturing process with an SPL and ECM (SPLECM) was then proposed to fabricate multiscale structures effectively, that an SPL increasing electric filed intensity enables ECM to improve the processing speed and fabrication of nanostructures on the electrochemical machined surface. In this study, the effects of the hybrid process with an SPL and ECM on the fabrication of multiscale structures on 304 stainless steel substrates were investigated experimentally. The proposed method capable of improving processing speed and fabricating multi-scale structures were stated. This study demonstrated the efficacy of SPLECM to create a shape and fabricate nanostructures on the surface simultaneously.
