The fabrication of interconnect from titanium powders and TiNx powders is investigated. Corrosion-resistant titanium and TiNx are used as reinforcement in order to reveal high heat and corrosion resistance at the elevated temperature. We fabricated the plates for interconnect reinforced with TiNx by mixing titanium powders with 10 wt.% of nano-sized TiNx. Spark Plasma Sintering (SPS) was chosen for the sintering of these composites. The plate made of titanium powders and TiNx powders demonstrates higher corrosion resistance than that of the plate of titanium powders alone. The physical properties of specimens were analyzed by performing hardness test and biaxial strength test. The electrochemical properties, such as corrosion resistance and hydrogen permeability at high temperature, were also investigated. The microstructures of the specimens were investigated by FESEM and profiles of chemical compositions were analyzed by EDX.
