PROCESSES FOR THE ELECTROLYTIC REMOVAL OF MATERIALS FROM OBJECTS

**Definition:** This place covers:

Electrolytic cleaning, degreasing, pickling or descaling

Electrolytic etching or polishing

Polishing or etching using a plasma which is generated at the surface of the workpiece by a voltage applied thereto in an electrolyte

Electrolytic stripping of metallic layers or coatings

Constructional parts, or assemblies thereof, of cells for electrolytic removal of material from objects, servicing or operating

**Limiting references (this place does not cover):** - Working of metal by the action of electric current on a workpiece, electrochemical machining, electrolytic grinding, electro-erosion -> B23H - Non-mechanical removal of metallic material from surfaces -> C23F - Inhibiting corrosion of metals by anodic or cathodic protection -> C23F13/00 - Constructional parts or assemblies thereof, of cells for both electrolytic coating and removal -> C25D17/00 - Wafer treatment -> H10P - Processes specially adapted for treatment of semi-conductors or solid state devices, e.g. electrolytic etching -> H10P50/00 , H10P50/20 , H10P52/00 , H10P95/70
