Anodizing Process Consistency: Variables Worth Recording

Practical workflow

1. Record alloy and part history when known; different alloys can respond differently.
2. Standardize cleaning, etching or desmutting steps appropriate to the process.
3. Track bath temperature and other chemistry variables required by the process specification.
4. Record electrical parameters and actual processing time.
5. Keep rinse stages controlled to reduce carryover between process tanks.
6. For dyed work, document dye identity, bath condition, time and temperature.
7. Record sealing method and final inspection observations.

Use the guide as a starting point

Machine, material, software and manufacturer requirements vary. Keep a controlled test record and use the current documentation for your exact equipment and process.
