Özet
In this study, TiB2- and graphene-reinforced Mg matrix (AZ91) composites were produced by the pressure infiltration method. The production process was carried out at 750 degrees C and 8 bar pressure in the SF6 gas atmosphere. The hardness, compression, and wear behaviors of the composite materials were examined. In addition, SEM examinations were conducted to understand the wear mechanisms of produced samples. The porosity ratio increased with the increasing graphene ratio. At the end of the measurements, the highest compressive strength was measured as 415 MPa and 140.6 HB in composite containing 0.25 vol% graphene compared to pure matrix and composite containing only TiB2. The highest abrasion resistance was achieved with the addition of 0.25 vol% graphene.
