Özet
In this study, the wear performance of A356 matrix composite materials produced by different amount SiC reinforcement semisolid moulding method was investigated. In the A356 matrix, was added four different amounts (5%, 10, 15 and 20) SiC. Composite powders mixed without ball (30 minutes) in the vibrating type mill were cold pressed (800 MPa) and green compacts were produced. The produced green compacts, in 550 degrees C mold temperature and in 600 degrees C furnace temperature, 100 MPa pressing force was pressed for 1 minute. Produced samples were characterized with microstructure, hardness and sphericity ratio. The wear tests were performed using a pin on-disk type wear testing device with 0.2 ms(-1) sliding speed, under two different loads (30 and 60 N) and at four different sliding distances (500 m, 1000, 1500 and 2000). As a result of the studies, the hardness increases with increasing amount of SiC in the composite material, while the sphericity rates decrease. As a result of the wear tests, while the highest weight loss, 5% SiC was obtained, the lowest weight loss was obtained in 20% SiC additional composite materials.
