The morphology and structure were analyzed by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD), and the chemical composition was identified via X-ray scattering spectroscopy (EDS). The corrosion resistance was studied using potentiodynamic polarization (PP) tests employing a 3.5% by weight NaCl solution. In the films, an increase of Ni up to 6.97 at% was observed, while in XRD the FCC phase of (Zr, Ti) N was identified, with a mixed orientation in planes (111) and (200), which tended to diminish with the increase of Ni. Finally, with the addition of Ni, the corrosion current densities were reduced from 5.56 x 10-8 to 2.64 x 10-9 A/cm 2. The improvement in the corrosion resistance is due to the effect of the Ni on the microstructure of the system (Zr, Ti) N, which can improve the quality of the passive film and prevent crystalline defects and corrosion zones. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49658894025 https://www.redalyc.org/journal/496/49658894025/ https://www.redalyc.org/journal/496/49658894025/html/ https://www.redalyc.org/journal/496/49658894025/49658894025.epub https://www.redalyc.org/journal/496/49658894025/movil 10.15446/dyna.v85n207.73304 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.207 Vol.85 |
