Electrochemical machining ECM is required for the manufacture of some complex micro-scale parts for biomedical devices and micro reactors that require an excellent surface finish. Additionally, the ECM current can be pulsed bidirectionally for bipolar pulsed ECM PECM to assist the electrochemical performance on passivated materials. The process be further assisted with a magnetic field, where Lorentz forces can drive a magnetohydrodynamic MHD electrolyte flow. Modeling the effects of bipolar PECM in a magnetic field is a necessary first step to efficiently negotiating this complex parameter space with a comprehensive design methodology.
