Özet

In this study, Al-SiCp composites were produced by a mechanical alloying method using SiCp powders up to 20 vol% as a reinforcement. The produced compositions were cold pressed at 630 M Pa with a single action and sintered at 560 degrees C for minutes under Ar gas atmosphere The experimental result showed that the reinforcement phase SiCp was homogeneously dispersed in the Al matrix and the interface between Al matrix and SiCp was well formed. Wear tests were carried out under dry sliding conditions using a pin-on-disk type testing machine at three different loads of 10N, 25N and 50N and at a sliding speed of 2.08 m/s Total sliding distance was selected as 400, 800, 1200 and 1600 m. After wear tests, the wear amount was determined by measuring the weight and dimension of specimens It was seen that the wear rate increased with increasing the applied load from 10N to 50N, sliding distance and decreased with increasing SiCp amount Microstructures and worn surface of Al-SiCp composites were investigated by SEM.
