1Corrosion Resistance ofAA6063-Type AI-Mg-Si Alloy by Silicon Carbide in Sodium Chloride Solution for Marine Application显示文摘The present work focused on corrosion inhibition of AA6063 type Al-Mg-Si alloy in sodium chloride(Na Cl) solution with a silicon carbide inhibitor, using the potentiodynamic electrochemical method. The aluminium alloy surface morphology was examined, in the as-received and as-corroded in the un-inhibited state, with scanning electron microscopy equipped with energy dispersive spectroscopy(SEM-EDS). The results obtained via linear polarization indicated a high corrosion potential for the unprotected as-received alloy. Equally, inhibition efficiency as high as 98.82% at 10.0 g/v silicon carbide addition was obtained with increased polarization resistance(Rp), while the current density reduced significantly for inhibited samples compared to the un-inhibited aluminium alloy. The adsorption mechanism of the inhibitor aluminium alloy follows the Langmuir adsorption isotherm. This shows that the corrosion rate of aluminium alloy with silicon carbide in Na Cl environment decreased significantly with addition of the inhibitor.Ojo Sunday Isaac Fayomi Malik Abdulwahab Abimbola Patricia ldowu Popoola Ferdinand Asuke 2015Journal of Marine Science and Application2015,14,4:0
