Inevitably by the pollution of the atmosphere in abrading-ball medium, ball grinder and process control agent etc., the impurity of introducing is also possible to
It reacts in mechanical milling process with powder and forms new object phase.Impurity pollutes phase composition and the structure that can change alloy, drop
Low-alloyed plasticity and toughness.Therefore the pollution to powder is must be strictly controlled and reduced in mechanical milling process.
Discharge plasma sintering（SPS）It is to integrate plasma activation, hot pressed sintering and resistance heating there is heating speed
Spend a kind of material system for the features such as material density that fast, sintering time is short, obtained is high, impressed pressure and sintering atmosphere are controllable
Standby new technology.For the sintering mechanism of SPS, it is considered that, SPS processes remove the Joule heat with hot pressed sintering and hot pressing causes
Plastic deformation acceleration of sintering process outside, DC pulse voltage is also generated between powder particle, and be effectively utilized powder granule
Between discharge generation surface activation and spontaneous heat effect, thus produce be beneficial to specific to SPS processes sintering show
As.
