Due to the high oxygen content of the superalloy powder produced by a novel Spark Plasma Discharge Process, the reduction process of superalloy powder was studied exploringly. Results show that under the protection of argon by atmospheric pressure at 550 oC and with CaH2 as its deoxidizer, the oxygen content of the Ni-based superalloy powder prepared by the novel method is decreased from 9.26% to 1.52%, and the final oxygen content depends mainly on the content of CaO left
