| Abstract | ||
| In this work the study mainly investigated the inhibition behavior, and the adsorption properties of different concentrations of an aqueous extraction of thyme plant range (5-20) ppm at the temperature range (288-318) K for corrosion of dental amalgam in artificial saliva, by applying electrochemical method. The result showed good inhibitive action for all thyme extract concentration with slight decreases by increasing temperature. The physisorption for thyme extract compound on the surface of dental amalgam obeys Langmuir isotherm. The kinetic parameter for corrosion process and thermodynamic data for adsorption process has been calculated. | ||
