VIGDOROVICH, V. I. et al. Protective Compositions Based on Modified Colza Oil Refining Products against Carbon Steel Atmospheric Corrosion. Port. Electrochim. Acta [online]. 2023, vol.41, n.6, pp.467-477.  Epub 31-Dez-2023. ISSN 0872-1904.  https://doi.org/10.4152/pea.2023410605.

IE(%) of CORP (with AN of 7.8 and 3.5., and modified with Zn powder, MGr or MCNT) used as coatings against CS atmospheric corrosion has been investigated. The studies were carried out by gravimetry and PSP methods. CORP composition was: phosphatides, hydrated oil and SF. IE(%) effect of CO coatings with the investigated compositions on CS corrosion kinetic parameters was estimated in a 0.5 M NaCl solution. Zn powder (50 wt.%) addition to CORP increased their IE(%) up to 80-86%. In this case, the coatings IE(%), at an anodic E of -0.2 V, reached 93-99%. The addition of MGr or MCNT to CORP modified by Zn powder had mostly a negative effect on IE(%).
