Özet
This study was carried out in order to provide an example for the composite materials produced using powder metallurgy, which is frequently employed in the automotive and aerospace fields. In this study, powder metal matrix composite specimens were produced by using unreinforced AA7075 alloy, 10%B4C reinforced AA7075 alloy and 20% B4C reinforced AA7075 alloy with powder metallurgy method. The density of AA7075 is 2.78, the density of %10 B4C + AA7075 is 2.67, the density of %20 B4C + AA7075 is 2.62 g/cm3. The hardness value of the unreinforced AA7075 samples was 45.56 before the heat treatment and 63.2 after the heat treatment; the hardness value of the 10% B4C reinforced AA7075 sample was 79.42 before the heat treatment and 87.24 after the heat treatment; and the hardness value of the 20% B4C reinforced AA7075 sample was 95.34 before the heat treatment and 102 after the heat treatment. Corrosion resistance of composites was investigated with potentiodynamic polarization. As a result of the corrosion test, the best corrosion resistance was measured in the 20% B4C reinforced AA7075 sample, and the lowest corrosion resistance was measured in the unreinforced AA7075 sample.
