The present work discusses a method of making a geometrically complex TiC ceramic preforms which are then infiltrated with aluminum. The parts were fabricated by Binder jet 3D printing technology After infiltration, solidification and slow cooling, a microstructural gradient was obtained throughout the part. In the region where the aluminum was in contact with titanium carbide various alloys were generated. After annealing at 900 °C and quenching in oil, material composition was conducted to verify the effects of binder jetting through SEM–EDS. A structural gradient microstructure was obtained, resulting in a hardness gradient of 700–1600 HV. Using XRD and EDS, it was found that the composites contained only αAl and TiC phases An analysis on influence of porosity was performed through SEM studies and permeability testing. The suggested processing approach allows for fabrication of complex-shaped graded composites with the desired property gradient suitable for a wide range of practical applications.
