Abstract
The growth and morphology of nitrided layers formed during the solid phase nitriding of pure titanium by CO2 laser were investigated. In the case of a laser treatment carried out under isothermal conditions, it was shown that CO2 photons irradiation of the substrate does not produce any specific assisted nitride growth: nitriding kinetics, nitride composition and structure were similar to those obtained after nitriding using a classical heating system. From the nitriding kinetics, nitrogen diffusion coefficients were determined using an analytical solution of Fick's equation. This allows to plot the evolution of the nitrogen concentration with respect to depth and to compare calculated profiles to those determined experimentally by Nuclear Reaction Microanalysis.
