Abstract

Spark plasma sintering(SPS) is a new process of rapid sintering.The instantaneous,intermittent and high powered electric pulse is applied to the die where the powders are put in.The high powered electric pulse can generate plasma among powder particles,resulting in cleaning effect,activation effect and uniformization effect,etc.This article briefly introduces the basic concept,principles and characteristics of SPS process.This article then turn to the more detailed describes about the new RD advances of the new materials produced by SPS.These new materials refer to the functionally graded materials,electric magnetic materials,fine ceramics,hard alloys and biomaterials,etc.
