Summary: The anti-corrosion properties of carbonyl iron (CI) and fluorinated carbonyl iron-hydrophobic composites (CI@PFOTES) under neutral salt spray were studied. The results showed the appearance of various corrosion products (Fe2O3, FeOOH, Fe3O4, etc.) after 192 hours of corrosion, indicating the corrosion process: Fe ??? Fe2 + ??? Fe3 +. In contrast, CI@PFOTES composites exhibited minor corrosion characteristics due to the hydrophobic nature of the PFOTES coating. However, the protective layer also experienced partial failure due to hydrolysis aging effect. In terms of electromagnetic properties, CI@PFOTES showed a more severe downward trend compared to CI due to the formation of various weak magnetic phase oxidation products.
