Abstract:

Laser nitriding of Ti-6Al-4V alloy was performed at different laser scanning speed. The results show that higher nitride concentration and microhardness are formed in the coatings laser nitrided with lower scanning speed. Nevertheless, higher nitride concentration results in higher residual stress which induces cracks occurring in the coatings.
