Passivation of Titanium Components
Complete guide to passivation of titanium alloys for enhanced corrosion resistance. Process parameters, standards compliance, and applications.
Quick Answer
What is passivation for titanium? Passivation is a chemical treatment that removes surface contamination and promotes the growth of the natural protective oxide layer on titanium. Unlike stainless steel passivation (which removes free iron), titanium passivation cleans and thickens the existing TiO鈧?layer.
Process
- Alkaline cleaning to remove oils and residues
- Nitric acid bath (20鈥?0% HNO鈧? 20鈥?0掳C, 15鈥?0 minutes)
- Thorough DI water rinsing
- Drying in clean environment
