Abstract

Spark plasma sintering was carried out to densify Ni-alloy doped with Pt powder at temperatures ranging between 1273 and 1323 K in order to obtain a variety of microstructures. Homogeneous distribution Pt and full densification were achieved in a short time, and the overall processing time not was exceeding 30 min via SPS process. Phase constitutions and microstructures and porosity evaluation were investigated by using scanning electron microscopy, chemical analysis and X-ray diffraction. It was found that two new phases ζ-PtAl2 and α-NiPt(Al). The set conditions are very promising from an energy-saving viewpoint; total powder consolidation was obtained per a decrease of 200 °C in the sintering temperature by using spark plasma sintering.
