► Computational model was developed to simulate the laser nitriding process. ► Model precisely predicts the depth of nitrogen diffusion into the Ti–6Al–4V. ► XRD, SEM and EDS analyses evidenced the formation of nitrogen rich layer ((-Ti and (-TiN). ► Length of nitrogen diffusion increased with incre...
