Spark plasma sintering (SPS) was applied to consolidating Stellite powder and bonding Stellite to stainless steel. Sintered compacts with relative densities more than 99.5 % were obtained by the SPS conditions, applied pressure=50 MPa, heating rate=50°C min-1, sintering temperature=1070°C and holding time=l0 min. They have good mechanical properties due to their finely-dispersed structures of carbide particles. Stellite and stainless steel could be easily bonded by SPS of Stellite powder placed on rod like stainless steel under the same conditions as the consolidation of Stellite powder. Diffusion zones in junctions were very narrow because of short-time and low-temperature sintering.
