Why do we need to add an oxide layer?
1. Enhanced Corrosion Resistance
Questão: Titanium alloys may corrode after long exposure to active flux and molten solder.
Oxide Layer Effect:
Anodized TiO₂ layer blocks chemical contact.
Strongly resists halide attack (Cl⁻, Br⁻).
Prevents inner surface roughening.
2. Improved Hardness and Wear Resistance
Questão: Titanium (≈36 HRC) still wears under solder impact.
Oxide Layer Effect:
Hardness increases to 800–1200 HV.
Reduces wear from solder and dross.
Lower friction, less solder sticking.
Longer cleaning intervals.
3. Better High-Temp Oxidation Resistance
Questão: Natural oxide is thin and uneven at 260–300°C.
Oxide Layer Effect:
Dense artificial layer blocks oxygen diffusion.
Prevents nozzle embrittlement.
Less dross buildup; stable wave.
4. Reduced Solder Wettability
Questão: Molten solder wets titanium easily, causing residue.
Oxide Layer Effect:
TiO₂ has low surface energy.
Solder doesn’t stick easily.
Easier to clean.
