Corrosion with Purpose: Electrochemical Machining Parts, Atom-By-Atom

When considering the various skills, procedures, materials, and systems in the field of corrosion engineering, it is reasonable to assume that the bulk of this work is meant to prevent or deter said corrosion from occurring. However, a material removal method exists that utilizes the principles of corrosion and electrochemistry to “reverse engineer” the work of corrosion engineering to perform what can be equated to ‘controlled corrosion’ on metallic parts as a material removal process in-and-of-itself. This unique process is known as electrochemical machining (ECM), as well as its more advanced version called pulsed electrochemical machining (PECM).
