Medhashree, H.Nityananda Shetty, A.N.2026-02-052019Journal of Adhesion Science and Technology, 2019, 33, 5, pp. 523-5481694243https://doi.org/10.1080/01694243.2018.1543529https://idr.nitk.ac.in/handle/123456789/24652The enhanced efficiency of the sodium dodecyl benzene sulphonate (SDBS) by the addition of trisodium phosphate and sodium benzoate on the corrosion inhibition of Mg-Al-Zn-Mn alloy in aqueous ethylene glycol solution (30%) containing chloride ions was studied by potentiodynamic polarization technique and electrochemical impedance spectroscopy method. The combination of SDBS with trisodium phosphate and sodium benzoate resulted in synergistic effects on the inhibition efficiency. The inhibition efficiencies decreased with the increase in the medium temperature. The mixture of inhibitors acted predominantly as anodic types and the adsorption of the inhibitors on the surface of the alloy obeyed Langmuir adsorption isotherm. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.Aluminum alloysAluminum corrosionBenzeneBenzoic acidChlorine compoundsEfficiencyElectrochemical corrosionElectrochemical impedance spectroscopyEthyleneEthylene glycolMagnesium alloysPolyolsSodiumSpectroscopic analysisZinc alloysCorrosion inhibitionEthylene glycol solutionsInhibition efficiencyLangmuir adsorption isothermsPotentiodynamic polarization techniqueSodium dodecyl benzene sulphonateSynergistic inhibitionZn-mn alloysManganese alloys
