Abstract
Abstract Structural characterization and corrosion behaviour of AA2024 nanocomposites reinforced with carbon nanotubes, silicon and their mixture are discussed in this research work. Ball milling was used to fabricate silicon nanoparticles and a two-step stir casting method has been used to synthesise AA2024-CNT, AA2024-Si and AA2024-CNT-Si (various proportions) hybrid metal matrix nanocomposites. The corrosion characteristics of the samples at room temperature were investigated using immersion, potentiodynamic polarization technique and also electrochemical impedance tests. Silicone oil was used as an inhibitor for the immersion test. Corrosion tested samples (before and after) were examined using a scanning electron microscope and analyzed. Results of the nanocomposite (AA2024 + 4% CNT + 2% silicon) through electrochemical impedance is 8.28 ohm and corrosion potential observed through the potentiodynamic polarization technique is −552.18 mV. This can be often less when put next with pure AA2024 and other nanocomposites prepared. These results are evidenced by immersion tests. Hence, it is concluded from the results obtained, AA2024 + 4% CNT + 2% silicon shows improved result than other nanocomposites.
