Electrochemical Analysis of a SiO2 Film on Alternative Rust Converter to Preserve Ferrous Alloys in Historical Heritage

The preservation of metallic materials of cultural heritage requires new strategies and protection alternatives. Rust converters offer protective properties to corrosion products, but it´s not enough. In this work, a SiO2 film was applied forming silane/rust converter system. Chemical and morphological characterization was performed by scanning electronic microscopy coupled to X-ray energy dispersive spectrometer (SEM-EDS). Protective film...
