    Caracterización de recubrimientos depositados por PVD para sensores de temperatura de frenos de una aeronave. by Montoya Rangel, Marvin

    Published 2018
    “…It can be concluded that the behavior of the corrosion rates obtained by resistance to linear polarization is very different depending on the different electrolytes. The PVD coatings presented a higher corrosion rate in H2SO4, and both AlCrN/TiSi and AlCrN/AlCr + Cr presented localized corrosion due to the existence of positive hysteresis in cyclic cyclic potentiodynamic polarization curves. …”
