Electrode for electro-chemical treatment of bearing surface of fluid dynamic bearing of metallic workpiece, has circular electrode surface which face metallic workpiece to be processed
The electrode (12) has circular electrode surface (20) which face the metallic workpiece to be processed. Multiple electrically non conductive pins are distributed within the insulating regions. The non-insulating regions extend radially outward than the pins and the pins protrude axially over the electrode surface. Independent claims are also included for the following: (1) a method for applying surface structures on bearing surface of bearing components of a fluid dynamic bearing (2) a bearing bush for a fluid dynamic slide bearing.
