Electrolytic Etching Intro
电解蚀刻（电化学）简介
标签：教程,电解,阳极,阴极,电流密度
以金属为阳极、不锈钢为阴极，在盐水或专用电解液中通低压直流电，使暴露区选择性溶解。相比化学蚀刻更环保、可控，但需绝缘非作业区并监控电流密度防止过蚀。
Make the metal the anode and stainless the cathode in brine or a dedicated electrolyte under low-voltage DC so exposed areas dissolve selectively. Greener and more controllable than chemical etching, but insulate non-work areas and monitor current density to avoid over-etch. ---
