Pure Ti suffers from a relative low strength and poor wear resistance. An addition of hard ceramics particles into it leads to improvement in its strength and wear resistance. However, Ti composites (TMCs) containing a high amount of ceramics particles exhibit low ductility. One way to have a good balance of tensile strength, ductility, and wear resistance is to fabricate functionally graded (FG) TMCs. In this study, the FG cylindrical rods were fabricated by powder compact extrusion using spark plasma sintering. The rods with high strength, good wear resistance and ductility were consisted of one or two layers containing TiC or TiB2 particles. In this study, reinforcement distribution and variation of layer thickness before and after the extrusion process of the FG rods were investigated. The FG rods of 10 mm in diameter and 50 mm in length with high relative density (> 97.5 %) were successfully obtained.
