Abstract

In this study, aluminium-nickel alloys with different Ni ratios ranging from 1 to 5 wt-% were produced by casting method. The effect of nickel on the microstructure and hardness properties was studied. The dry sliding wear response of the Al-xNi alloys against steel and alumina counterfaces was investigated. Worn surfaces of the alloys were examined using scanning electron microscopy. The results showed that the hardness of the alloys increases with increasing nickel content. Severe wear damage was observed at low and high nickel contents. Maximum wear resistance was obtained with the addition of 3 wt-% nickel to the pure aluminium under both loads and against both counterfaces.
