| description | The invention relates to the field of part preparation in a composite material production technology, and particularly discloses a preparation method for a gradient nozzle. The method comprises the steps that metal powder and ceramic reinforced particles are uniformly mixed according to the design of the gradient nozzle so as to prepare 2-15 kinds of composite powder with different ceramic contents, the powder is subjected to high-energy ball mill mechanical alloying, gel solutions are added into the composite powder separately, the gel solutions and the composite powder are uniformly stirred to form composite material slurry with the good fluidity, then curing agents are sequentially added into the multiple kinds of slurry from outside to inside, the multiple kinds of slurry with the curing agents are sequentially poured into a vertical type centrifugal forming machine rotating at a high speed, and after curing is finished, demolding, drying and vacuum sintering are carried out so as to prepare the gradient |
