Electrochemical part marking (also known as electrochemical etching, chemical etching, electrolytic etching and chemetch) is a permanent process for high-resolution part marking onto conductive metal surfaces. It is ideal for identification and traceability of certain metal components.
Advantages:
- Can create surface marks (oxide), deeper marks (etch) or combinations of both
- Good for thin-walled parts that might be deformed by dot peen or scribe systems, or parts that cannot have any raised surfaces
- Inexpensive solution
- Clear marks
Disadvantages
- Can be a messy application using the electrolytes in a manual operation
