Anodizing vs Passivation for Titanium
Comparison of anodizing and passivation surface treatments for titanium components.
AnodizingvsPassivation
Quick Answer
Anodizing builds a thicker, coloured oxide layer for wear and aesthetic purposes. Passivation cleans and enhances the natural oxide for corrosion protection.
Key Differences
| Factor | Anodizing | Passivation |
|---|---|---|
| Purpose | Wear/colour | Corrosion resistance |
| Oxide Thickness | 0.2-100 碌m | 0.005-0.01 碌m |
| Visual Change | Coloured | None visible |
| Process | Electrochemical | Chemical (acid) |
| Wear Resistance | Excellent | None |
| Corrosion | Good | Excellent |
