In this study, dry sliding wear behavior and corrosion resistance of Al-Cu-SiC-xNi (x: 0, 0.5, 1, 1.5 wt.%) composites were investigated. Effect of nickel content on the microstructure and hardness of the alloys was also studied. Wear tests were conducted using a ball on disc wear test device. Corrosion behavior of Al-Cu-SiC-xNi composite alloys in 3.5% NaCl solution was investigated by using potentiodynamic polarization, impedance spectroscopy and cronoamperometric methods. The results showed that the hardness of the composite alloy increases with increasing nickel content. Maximum wear resistance is reported with the addition of 1 wt.%Ni. It was determined that corrosion resistance of Al-Cu-SiC composite alloys improved with increasing nickel content in the alloy. (C) 2014 Elsevier Ltd. All rights reserved.
