Symmetrical layered gradient composite material and preparation method and application thereof
The invention relates to a symmetrical layered gradient composite material as well as a preparation method and application thereof, the method adopts a plasma activated sintering process to prepare amolybdenum/silicon nitride/molybdenum symmetrical layered gradient composite material, and the activation effect on powder particles before sintering is realized through the coupling effect of a temperature field, an electric field and a pressure field. Furthermore, the preparation of the gradient composite material is completed at a relatively low sintering temperature within a relatively short sintering time, and the molybdenum/silicon nitride/molybdenum symmetric layered gradient composite material with high density, low impurity content and good interface bonding is finally and quickly prepared by combining a plasma activated sintering method and the gradient of the gradient composite material.
