In this study, the hot pressing technique was used to produce Al-CeO2composites. Furthermore, the effects of CeO2content on in-situ phase formation and the properties of the composites were systematically investigated. The samples were fabricated at 600 °C at 1, 5 and 10 wt% CeO2content. The in-situ phases could not be observed at 1 and 5 wt% CeO2ratios. However, intermetallic phases and complex oxides like Al11Ce3and Al11CeO18were identified in the sample containing 10 wt% CeO2. It was revealed that 5 wt% CeO2containing composite exhibited superior wear resistance and the wear rate of the aluminium was decreased from 9.851·10−4mm3/Nm to 2.562·10−4mm3/Nm. It was observed that the in-situ formed oxide deteriorated the wear properties of the composite, and the wear resistance of Al-CeO2-10 was reduced. Also, increasing CeO2content provided the formation of in-situ oxides and stabilized the surface. Accordingly, the wear rate of the aluminium was improved up to 0.0548 mm/year owing to the existence of 10 wt% CeO2. The surface stability of the composite was enhanced with CeO2particles, and the corrosion damage shifted the CeO2and complex oxides containing regions.
