| description |
NbxSiyNz thin film nanostructure was grown using the unbalanced magnetron sputtering (UBM) technique with varying Si content. Corrosion resistance was evaluated by potentiodynamic polarisation technique in a 3% NaCl solution. Microstructure was analysed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and laser scanning microscopy. Chemical composition was ascertained by X-ray fluorescence (XRF) technique. The results showed that deposition rates increased with higher Si content. A microstructural change was observed for greater than 5% Si content through the transition from a crystalline to an amorphous structure in the thin films. Corrosion test results demonstrated that the thin films having the highest silicon content had better corrosion resistance. |

La microestructura de los recubrimientos se analizó por medio de XRD (X ray diffraction - difracción de rayos X), SEM (scanning electron microscopy - microscopia electrónica de barrido) y microscopia láser confocal. La composición química se identificó con la técnica XRF (X ray fluorescence - fluorescencia de rayos X). Como resultado las tasas de depósito se incrementaron con la adición de Si, además se observó un cambio en la microestructura para contenidos superiores a 5% de Si, mediante la transición de un recubrimiento cristalino a amorfo. Finalmente, los resultados de corrosión sugieren que los recubrimientos con un alto contenido de silicio tienen un mejor comportamiento frente a la corrosión del sistema.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/35932Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 32, núm. 3 (2012); 10-13 Ingeniería e Investigación; Vol. 32, núm. 3 (2012); 10-13 2248-8723 0120-5609Velasco Estrada, Leonardo and Olaya Florez, Jhon Jairo and Rodríguez Baracaldo, Rodolfo (2012) The corrosion resistance and microstructure of ubm system-deposited nbxsiynz thin films.
