| Summary: | The anti-corrosive performances of aluminum and its alloys are the subject of considerable technological importance due to the increased industrial applications of these materials. This paper reports the results of the linear polarization (LP) and electrochemical impedance spectroscopy (EIS) measurements on the corrosion inhibition of Al-Mg-Si alloy in seawater using natural products (natural honey, vanillin and tapioca starch) as an inhibitor. The results show that the anti-corrosive performances increase with the increasing of natural products concentration. The energy dispersive spectrometer (EDS) studies elucidated that the breakdowns of Al2O3 after exposed to seawater decreased with the presence of natural products. In all cases, the anti-corrosive performances can be given in the following increasing order: Natural honey < Vanillin < Tapioca starch |
