Class Information
Number: 205/666
Name: Electrolysis: processes, compositions used therein, and methods of preparing the compositions > Electrolytic erosion of a workpiece for shape or surface change (e.g., etching, polishing, etc.) (process and electrolyte composition) > Using mask
Description: Process in which a workpiece surface to be eroded is provided with a distinguishable nonuniform covering which allows only part of the workpiece to contact the electrolyte.
