Abstract

In this present investigation aluminum Al6061 alloy and 5 wt% of Fe₂O₃ in addition to 2%, 4%, 6% weight of B₄C reinforced matrix composites (AMCs) is fabricated by stir casting method. Upon increasing the amount of weight percentage to the composites, the mechanical properties also increased. The AC impedance spectra and polarization studies have been utilized to investigate the resistance towards corrosion of the Fe₂O₃ and B₄C reinforced Al6061 metal matrix composites (AMCs). Corrosion current (Icorr), Linear Polarization Resistance (LPR), corrosion potential (Ecorr), capacitance (C), charge transfer resistance (Rct) parameters were considered by the materials submerged in 3.5% of Brine solution and the resistance towards corrosion of the material is determined. Scanning Electron Microscopy (SEM) is utilized to identify the before and after corrosion of the prepared composites. The resistance towards the corrosion is significantly increased with increasing the wt% of reinforced composites.

Fe2O3和B4C的添加对Al-Mg-Si合金在3.5%盐水中的力学性能和耐腐蚀性能的影响

摘要

在本研究中，除了 2%、4%、6% 重量的 B ₄ C 增强基复合材料 (AMC) 之外，还通过搅拌铸造法制造了铝 Al6061 合金和 5 wt% Fe ₂ O ₃。当增加复合材料的重量百分比时，机械性能也增加。交流阻抗谱和极化研究已被用于研究 Fe ₂ O ₃和 B ₄的耐腐蚀性C 增强的 Al6061 金属基复合材料 (AMC)。腐蚀电流 (Icorr)、线性极化电阻 (LPR)、腐蚀电位 (Ecorr)、电容 (C)、电荷转移电阻 (Rct) 参数由浸没在 3.5% 的盐水中的材料和耐腐蚀的材料考虑。材料确定。扫描电子显微镜 (SEM) 用于识别制备的复合材料腐蚀前后。随着增强复合材料的重量百分比的增加，对腐蚀的抵抗力显着增加。
