Özet
In this study; Hybrid composites containing different proportions of TiB2 and graphene were produced using the pressure infiltration method. Inert SF6 gas is used to prevent oxidation in the productions. While 8 bar infiltration pressure was provided by argon gas, the infiltration temperature was chosen as 800°C. The corrosion behaviors of the compos-ite materials were examined. Corrosion resistance was determined by potentiodynamic and immersion corrosion testing in 3.5% NaCl solution. In addition, SEM examinations were conducted to understand the corrosion mechanisms. At the end of the measurements, the highest porosity was measured as %4,7 in composite containing 1% graphene compared to pure matrix and composite containing only TiB2. The added reinforcement (TiB2 and Graphene) elements cause decreases in corrosion resistance. The highest corrosion resist-ance was achieved in AZ91 alloys.
