In this Ph.D. thesis work, zirconium nitride with silicon (ZrN-Si) coatings doped with silver (ZrSiN-Ag) and copper (ZrSiN-Cu) were deposited, using the sputtering technique on glass, silicon and 316L stainless steel substrates. The main objective of the study was to research the effect that silver (Ag) or copper (Cu) have on the chemical composition, microstructure and functional properties, such as mechanical, optical and electrical properties of the deposited coatings. The chemical characterization of the coatings was performed by means of Energy-Dispersive X-ray (EDX) spectroscopy and X-ray Photoelectron spectrometry (XPS) techniques. The characterization of the microstructure of the coatings was carried out by means of X-Ray Diffraction (XRD) and Transmission Electron Microscopy (MET) techniques. The morphology was studied by means of the Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM). To assess the mechanical properties of the coatings, nano hardness measurements were carried out. The optical response was evaluated by means of transmittance and reflectance measurements, using the ultraviolet-visible spectrophotometry technique (UV-VIS). Finally, electrical properties were evaluated by voltage vs. current measurements using the Van der Pauw method. The most relevant results of this work can be summarized in four points. i) ZrSiN-Ag and ZrSiN-Cu coatings have a microstructure with manometric dimensions (crystallite sizes smaller than 15 nm). ii) The addition of silicon to the ZrN coating had no nano-compound microstructure. iii) The addition of silver or copper to the ZrSiN structure modified both the microstructure and the morphology of these coatings. Finally, iv) the addition of silver or copper formed no compounds with zirconium (Zr), nitrogen (N) or silicon (Si) atoms, which indicates that these elements were immiscible and that most likely they have been lodged in the grain edges of the ZrSiN system. The characterization of the functional properties studied allowed us to establish that the nanohardness of the coatings had no improvement with the addition of silicon, silver or copper. The coatings with Ag added may have a possible application as dichroic filters, which block ultraviolet radiation, but allow infrared radiation to pass through. Cu coatings showed a high reflection (70%) in the infrared region, which decreases in the ultraviolet region. These last coatings were bright golden, with possible applications as decorative coating. Finally, the electrical measurements showed that the addition of silver and / or copper to the ZrSiN system produced a decrease in its electrical resistivity.
