chromating
Anti-corrosion metal treatment
Chromating is the process of applying a chromate conversion coating to metal surfaces, typically aluminum or zinc, to improve corrosion resistance and paint adhesion.
The treatment creates a thin protective layer through a chemical reaction with chromium compounds.
The parts require chromating before final assembly.
Though effective, chromating with hexavalent chromium has faced increasing environmental restrictions, prompting shifts toward alternative surface treatments.
