Hypothesis
How do laser parameters affect the surface properties of the Ti-3Al-2.5V alloy?
Conclusion
Laser remelting can effectively eliminate micro-cracks and improve the hardness of titanium alloy surfaces.
Supporting Evidence
- Laser remelting can eliminate local surface micro-cracks.
- Higher pulse frequency and intensity increase the melt pool temperature and size.
- Using protective gas prevents significant material ablation.
- Increased laser intensity and frequency lead to higher material hardness.
- Surface roughness increases with higher intensity and pulse frequency.
Takeaway
This study shows that using lasers can make titanium surfaces smoother and stronger by melting and reshaping them.
Methodology
The study used a fiber laser system integrated into a CNC lathe to perform laser remelting on Ti-3Al-2.5V alloy samples.
Limitations
The study primarily focused on a specific titanium alloy and may not be generalizable to all titanium alloys.
