  • Common sage extract as an inhibitor of steel corrosion in 3% NaCl [Elektronski vir]
    Tomić, Milorad V. ...
    Research on corrosion protection of steel was carried out by processing corrosive environment applying various concentrations of common sage extract 0.5 g/dm3, 1 g/dm3 and 1.5 g/dm3, as a green ... inhibitor, in 3 % NaCl solution. Measurements were conducted using the gravimetric method, as well as electrochemical methods (Tafel extrapolation method and electrochemical impedance spectroscopy). The highest level of protection was achieved in 3% NaCl, at concentrations of common sage 1.5 g/dm3, over a period of 6h and is z = 97.5 % . Concentrations of common sage 1.0 g/dm3 and 1.5 g/dm3 in 3% NaCl show very good inhibitory effect, since the average protective factor is z = 78.5% and z =95.3% respectively. These results recommend the common sage as a possible inhibitor in 3 % NaCl solutions. Results obtained by electrochemical impedance spectroscopy are consistent with the results of gravimetric measurements of corrosion indicators in 3% NaCl. This confirms that the electrochemical impedance spectroscopy can be used for rapid corrosion tests as a reliable method. Determination of corrosion rate and the degree of protection using Tafelʼs diagrams, calculated on the basis of current corrosion, do not provide reliable results. The obtained results differ from those obtained by gravimetric method and electrochemical impedance spectroscopy (EIS ) .
