“…Additionally, the SEM was equipped with energy dispersive x-ray (EDX) analysis, which has been utilized to determine the nitrogen content at several points of each sample. Due to the superposition of the titanium L line and the nitrogen K line in the spectra and the deficient energy resolution of the detector (30 eV are required) [11], only qualitative statements were possible. However, different regions such as the melting, diffusion and heat affected zone could be compared.…”

Titanium was laser nitrided by means of free electron laser (FEL) irradiation in pure nitrogen atmosphere. The variation of macropulse frequency and duration of the FEL micropulse trains resulted in the formation of δ-TiN x coatings with different thicknesses and different micro-and macroscopic morphologies. The coatings revealed characteristic values for hardness, roughness and crystallographic texture, which originate from the growth mechanism, the solid-liquid interface energy and the strain. Further investigations showed that the dendritic growth begins at the surface and the alignment of the dendrites is normal to the surface. A correlation of the texture with the time structure of the laser pulses was found. Combined numerical simulations of temperature evolution and nitrogen diffusion were performed and the results were compared with the experimental findings. The simulations can explain the experimental results to a great extent.

“…By means of peak position and peak broadening it is possible to extract the strain and grain size in the sample [27,28]. The relation between peak width B hkl (Cauchy profiles are used here), peak position θ hkl , and strain is given by equation (11) [28]:…”
