Abstract
The invention belongs to the fields of amorphous alloy composites, additive manufacturing technology and hot isostatic pressing sintering forming, and in particular relates to a preparation method of tungsten particle reinforced amorphous matrix composites, comprising the following steps: (1) making tungsten powder and amorphous alloy powder into a preform by the micro-jetting and bonding 3D printing technology, specifically comprising: in the preforming process by micro-jetting and bonding, through a double-drum type powder feeding device, spraying tungsten powder and amorphous alloy powder into a layer of uniformly mixed powder layer by double nozzles, then bonding the powder layer into a bonding layer by the binder, and repeating the operations of spraying the powders and binder, so that a preform with uniform particle phase distribution is finally prepared; (2) placing the preform in a capsule, and performing heating and vacuumizing on the capsule in a heating furnace; and (3) placing the capsule in the hot isostatic pressing sintering furnace and performing hot press forming to obtain an amorphous matrix composite. In the present invention, through combining the cold additive micro-jetting and bonding technology with hot isostatic pressing sintering forming, a tungsten particle reinforced amorphous matrix composite with large size and uniform particle phase distribution can be prepared.
