Description
Summary:This study aims to elaborate the influence mechanism of magnetic field on the electrochemical machining (ECM) localization, which is characterized by the ECM drilling technique. Two experiment models are constructed based on the effect of magnetic field on the anodic dissolution: Model 1 is based on the 304 SS│FeCl 3 system, in which magnetic field suppresses the anodic dissolution, while Model 2 is based on the Cu│NaCl system, in which magnetic field promotes the anodic dissolution. The experimental results show that the magnetic field improves the ECM localization of the 304 SS│FeCl 3 system in ECM drilling, while having no beneficial influence on that of the Cu│NaCl system. It is found through experimental result analysis and comparison that the influence of magnetic field on anodic dissolution is of good correspondence with the influence of magnetic field on the ECM localization. To be specific, when the magnetic field suppresses the anodic dissolution, ECM localization is enhanced by the magnetic field; when the magnetic field promotes the anodic dissolution, ECM localization does not benefit from enhancement by the magnetic field. Such conclusion is of positive significance for the extensive application of magnetic field-assisted ECM.
