This study focuses on fabricating AlAl matrix compositeComposites layers on commercially pure AlAl and 70757075 alloy by hot pressing to improve wear resistance at elevated temperaturesTemperature. As a reinforcement particle, Al2Ce intermetallicAl2Ce intermetallic particles synthesized by vacuum arc melting was chosen for its better chemical compatibility with AlAl matrix. Structural characterizationsCharacterization revealed the good binding between Al2Ce-p and AlAl matrix and the success of Al2Ce-p in increasing hardnessHardness of AlAl and 70757075 alloy. Results of the wear tests conducted at 200 °C against alumina balls under the load of 2 N showed 2.6- and 6.0-times lower wear rate for the AlAl matrix compositeComposites layer covered and 70757075 matrix compositeComposites layer covered samples as compared to their monolithic states, respectively.
