| Abstract: | Salvia officinalis L. honey has been tested as
inhibitor for the corrosion of CuNiFe alloy in 0.5 M NaCl solution by
electrochemical measurements. The honey solutions are prepared in different
concentrations, such as 400, 600, 800, 1000 and 1200 ppm. Polarization curves
show that the honey acts as mixed corrosion inhibitor, and the inhibition
efficiency increases with an increase in honey concentration. The maximum
corrosion inhibition efficiency of approximately 70 % is achieved with the
highest inhibitor concentration (1200 ppm of honey). Changes in impedance
parameters are indicative of adsorption of honey compounds on the metal
surface. The adsorption of natural honey on the CuNiFe alloy follows the
Langmuir adsorption isotherm. |
