Morphology of titanium nitride produced using glow discharge nitriding, laser remelting and pulsed laser deposition

Surface layers, produced on titanium alloys by means of glow discharge nitriding, laser modification by remelting using Nd:YAG or diode lasers in nitrogen environment and pulsed laser deposition by titanium target ablation in nitrogen environment, have been studied. Residual stresses were measured using an X-ray method and their values were related to the type of the applied technological process.
