Enhancement of wear and corrosion resistance of beta titanium alloy by laser gas alloying with nitrogen

- Laser technology is a fast, clean and flexible method for surface hardening of TNZT.
- Laser can form a protective hard layer on TNZT surface without altering surface roughness.
- The laser-formed layer is metallurgically bonded to the substrate.
- Laser-treated TNZT is highly resistant to corrosion and wear in Hank's solution.
