Resumen en inglés Titanium nitride (TiN) has been applied as decorative coating due to its high reflectivity and goldish color, having high hardness and wear resistance. In the present work, TiNx films were deposited by grid-assisted magnetron sputtering. The color and reflectivity were investigated by spectrophotometry as a function of the working gas ratio N2/Ar used during films deposition. The crystalline phases were identified by X-ray diffraction pattern (XRD). The TiNx plasma frequency (ωp) and the relaxation time (τ) were determined by fitting the experimental reflectivity curves, according to the Drude model. The color parameters obtained by the CieLab method were used to compare TiNx films with gold film
