Embodiment 1
[0031] S1. Preparation of composite balls
[0032] The boron carbide is spheroidized, and then the hydrophilic modified polystyrene resin powder is mixed with the prepared boron carbide spheres, so that the polystyrene resin powder is wrapped on the surface of the boron carbide spheres. The volume of boron carbide is the same as that of boron carbide, and then the obtained spherical particles are put into a mixture of tungsten alloy powder (wherein, by mass ratio, tungsten: (iron+copper)=90wt%:10wt%) and bonding molding agent phenolic resin Roll forming on the powder to obtain a raw embryo, which is transferred to a muffle furnace for physical degreasing (heating from room temperature to 200 °C at a heating rate of 1 °C / min and then holding for 6h), physicochemical degreasing (at a heating rate of 1 °C / min) The heating rate was increased from 200 °C to 350 °C and then held for 3 hours), the shell was solidified (the temperature was increased from 350 °C to 900 °C at a heating ...
Embodiment 2
[0036] S1. Preparation of composite balls
[0037] The boron carbide is spheroidized, and then the hydrophilic modified polystyrene resin powder is mixed with the prepared boron carbide spheres, so that the polystyrene resin powder is wrapped on the surface of the boron carbide spheres. The volume is the same as that of boron carbide, and then the obtained spherical particles are put into a mixture of tungsten alloy powder (wherein, in terms of mass ratio, tungsten: (iron+copper)=95wt%:5wt%) and bonding molding agent phenolic resin Roll forming on the powder to obtain a raw embryo, which is transferred to a muffle furnace for physical degreasing (heating from room temperature to 200 °C at a heating rate of 1 °C / min and then holding for 6h), physicochemical degreasing (at a heating rate of 1 °C / min) The heating rate was increased from 200 °C to 350 °C and then held for 3 hours), the shell was solidified (the temperature was increased from 350 °C to 900 °C at a heating rate of 1...
