摘要：An evaluation of Lentinula edodes (L. edodes) extract as a green corrosion inhibitorfor 1018 carbon steel in 0.5 M H2SO4 was carried out by using weight loss tests,potentiodynamic polarization curves and electrochemical impedance spectroscopymeasurements. These tests were complemented by electronic microscopy analysis,infrared and UV-vis spectroscopy as well as mass chromatography. It has been foundthat L. edodes is an efficient, mixed type of inhibitor, which increases with itsconcentration and immersion time, but decreasing with the testing temperature. Theway that L. edodes adsorbs on to the metal surface is chemical by following aLangmuir type of adsorption isotherm, to form protective corrosion products due to theexistence of compounds, with heteroatoms such as C, O and N, in functional groupssuch as amine, which are the responsible for the corrosion protection.
