Özet

In this work, the powder metallurgy method has been used to synthesis nano-sized B4C and SiC reinforcement AA2024 matrix hybrid nanocomposite. The effect of B4C and SiC reinforcement content on mechanical and corrosion behavior of AA2024-B4C/SiC hybrid nanocomposite was examined. The corrosion test results show that corrosion current density (3.17 A/cm2 x 10(-6)) of AA20240-4 wt% B4C/SiC hybrid nanocomposite sample was 46.12 A/cm2 x 10(-6) (lower than current density of AA2024 sample). The corrosion current rate of AA2024 alloy was almost 14 times higher than AA2024-4 wt% of B4C/SiC hybrid nanocomposites. Mechanical tests showed that the hardness value of hybrid nanocomposites increases as increased reinforcement content and AA2024-5 wt% B4C/SiC hybrid nanocomposite has a maximum hardness of 179.4 HB.
