Reduced Potential for Subclass Carryover

ECM (Electrochemical Machining) – Controlled metal removal by anodic dissolution. Direct current passes through flowing film of conductive solution which separates the work piece from the electrode tool. The work piece is the anode, and the tool is the cathode.

Subclass characteristics would not be displayed on a work piece machined using ECM.  This is due to the random nature of the erosion of the work piece by the electrolyte fluid when current is applied.  The surface of the work piece may have a pitted, granular-like appearance when viewed under magnification.
