Anodic Dissolution Model Parameterization for Magnetically-Assisted Pulsed Electrochemical Machining (PECM)

Abstract

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.
