通过适当的电化学加工在大面积的金属表面上进行微纹理化。在毫米级工具电极表面制作出尺寸为数十微米的微纹理图案，并通过一次工艺将其同时复制到工件上。为了获得更好的加工精度，需要较短的脉冲宽度，然后由于电源电路的电感限制了最小可加工脉冲宽度，因此采用分支电动进给。几十平方毫米的加工面积就可以实现小于一百微米的微观纹理。 (C) 2019 年由 Elsevier Ltd 代表 CIRP 发布。
Micro texturing is performed over a large area of a metal surface by an appropriate electrochemical machining. A micro texture pattern with a size of several tens of micrometers is fabricated on a millimeter-scale tool electrode surface and is simultaneously replicated on the workpiece in one process. A shorter pulse width is required for better machining accuracy, and then branched electric feeding is adopted because the minimum machinable pulse width is limited due to the inductance of the power supply circuit. Micro textures smaller than a hundred micrometers could be achieved with a machining area of several tens of square millimeters. (C) 2019 Published by Elsevier Ltd on behalf of CIRP.
