Design of Forming Sheet Electrodes in Electrochemical Finishing of ZDC2 Castings Surface

摘要: This research presents a new modus of electrochemical finishing as finish process using an effective design forming sheet electrode on zinc alloys beyond traditional die casting the surface castings instead conventional hand or machines polishing. In current experiment, author takes outer shell toy vehicle for instance; five types are used and supplied with continuous direct in experiment finishing. For electrodes, thin plate small end radius wedge angle associated higher density provides larger discharge space better polishing effect. The spherical head performs best. after saves need just needs quite short time to make smoothing bright. An low-cost is presented.
