Description

C25F encompasses electrochemical processes and equipment designed to selectively remove material layers or deposits from solid objects through electrolysis. This includes electropolishing, electrorefining, electrostripping of coatings, and electrolytic cleaning or descaling applications across metallic and non-metallic substrates. The classification covers both the procedural parameters (current control, electrolyte composition, electrode configuration) and the apparatus configuration required for material removal, distinguishing it from electrodeposition (C25D) which adds material rather than removing it.

Scope Notes

Limiting references: Treatment of water, waste water or sewage by electrochemical means, e.g. electrolysis Inhibiting corrosion of metals by anodic or cathodic protection Constructional parts, or assemblies thereof, of cells for both electrolytic coating and electrolytic removal | Application references: Electrolytic etching of semiconductor wafers or parts of semiconductor or solid-state devices
