Özet
In this study, hardness and corrosion properties of alumina reinforced AA5083 aluminum alloy based functionally graded materials were investigated. The powder metallurgy method was used in functionally graded materials production and the samples were produced in 3, 4 and 6 layers. Vickers hardness tests and potentiodynamic corrosion tests were conducted on the samples of the produced functionally graded materials. It was seen that there was an increase in hardness values with increasing alumina reinforcement ratio in layers of functionally graded materials. According to corrosion test results, there was a small decrease in the corrosion rate of the materials with increasing number of layers in the functionally graded materials. Corrosion effect was found to be higher in layers with high alumina reinforcement.
