    Caracterización electroquímica de la pasivación de acero inoxidable empleado en la fabricación de fuselajes de helicópteros. por Lara Banda, María del Refugio

    Publicado 2018
    “…The results indicate that the 15-5PH stainless steel passivated in citric acid in the presence of NaCl at a temperature of 25 ° C with an immersion time of 30 minutes in the passivating medium present the best corrosion rate. The XPS technique shows passive layer thickness up to 12.45 nm. This layer obtained consists of iron and chromium oxides in which the nickel does not vary in its concentration.…”
