Classification Context
- Section:
- CHEMISTRY; METALLURGY
- Class:
- COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; CHEMICAL SURFACE TREATMENT; DIFFUSION TREATMENT OF METALLIC MATERIAL; COATING BY VACUUM EVAPORATION, BY SPUTTERING, BY ION IMPLANTATION OR BY CHEMICAL VAPOUR DEPOSITION, IN GENERAL; INHIBITING CORROSION OF METALLIC MATERIAL OR INCRUSTATION IN GENERAL
- Subclass:
- CLEANING OR DEGREASING OF METALLIC MATERIAL BY CHEMICAL METHODS OTHER THAN ELECTROLYSIS
Description
C23G covers chemical cleaning and degreasing processes for metallic materials using non-electrochemical methods, including acid pickling, alkaline cleaning, solvent degreasing, and passivation treatments. These processes remove contaminants such as oxides, oils, greases, and other surface impurities prior to further metallurgical operations or coating application. The classification excludes electrochemical cleaning methods (covered under C23F) and mechanical cleaning techniques, focusing specifically on chemical attack and dissolution mechanisms.
