Este trabajo investiga la deposición de películas delgadas de nitruro de titanio (TiN) mediante descarga de plasma de jaula catódica sobre sustratos de vidrio a baja temperatura (300 °C) y una distancia corta entre el sustrato y la tapa (7 mm). El objetivo fue evaluar el efecto de la relación H₂/N₂ del plasma en las propiedades de la película. Las deposiciones se realizaron a 1 Torr y las películas se caracterizaron mediante difracción de rayos X, reflectometría y espectroscopia de impedancia electroquímica (EIS). El análisis EIS permitió estimar la resistividad eléctrica y la estabilidad química, demostrando condiciones de deposición que favorecen una mayor resistencia a la corrosión. La singularidad de este estudio reside en la combinación de: (i) geometría de jaula catódica con un alto número de agujeros; (ii) una distancia corta entre el sustrato y la tapa (7 mm), que potencia los efectos de cátodo hueco; y (iii) un enfoque electroquímico (EIS) para correlacionar el proceso, la microestructura y las propiedades.
