- Abstract: The present work aims nitriding to investigate the effect on titanium grade 2 with rotating bending fatigue tests at room temperature and short-term creep tests at 500°C. The nitriding treatment was carried out at 850°C for 9 hours. After thermochemical treatment, XRD analysis revealed the formation layer composed of TiN and Ti2N. Microscopy analysis revealed the presence of a uniform layer with a mean thickness of 3.6 mM and 50% increase in surface roughness. Fatigue life (107 cycles) was reduced by 42% by increasing surface roughness. On the other hand, nitriding treatment increased creep life by at least two times due to oxidation rate reducion and blocking dislocations movement by nitrogen in solid solution during the plastic deformation process.
