    manufacturing by laser powder bed fusion enables complex AlSi10Mg components but
    produces a heterogeneous microstructure prone to localized corrosion. In this
    study, hydrophobic polydimethylsiloxane (PDMS) ultrathin films, with and without
    an SiO\r\n                    <jats:italic>ₓ</jats:italic>\r\n                    interlayer
    attached by chemical vapor deposition (CVD), were applied for corrosion mitigation.
    Surface modifications were characterized by X‐ray photoelectron spectroscopy (XPS),
    polarization modulation–infrared reflection–absorption spectroscopy (PM‐IRRAS)
    and water contact angle (WCA) measurements. Electrochemical behavior was evaluated
    by electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV),
    and chronoamperometry by a droplet‐cell approach. Atmospheric corrosion processes
    simulating marine corrosion were monitored by optical microscopy. Spectroscopic
    analyses confirm successful PDMS attachment. Electrochemical measurements reveal
    reduced corrosion current densities by one magnitude, suppressed pitting activity,
    and anodic shifts of the pitting potential. The SiO\r\n                    <jats:italic>ₓ</jats:italic>\r\n

    corrosion.\r\n                  </jats:p>"
