Abstract

The invention discloses a method and a device for preparing tungsten powder reinforced aluminum matrix composite. The method comprises the following steps: mounting a quantitative tungsten powder supply device on a high-pressure inert gas input pipe of a device for atomizing, spraying and depositing aluminum or aluminum alloy liquid, taking high-pressure inert gas as a flow carrying medium, spraying the tungsten powder to the surfaces of aluminum or aluminum alloy micro-droplets formed by atomizing, enabling the tungsten powder to disperse and attach onto the surfaces of the aluminum or aluminum alloy micro-droplets, then spraying and depositing the tungsten powder and the aluminum or aluminum alloy micro-droplets to a substrate and solidifying to prepare the tungsten powder reinforced aluminum matrix composite. The device comprises a device for atomizing, spraying and depositing aluminum or aluminum alloy liquid, wherein a quantitative tungsten powder supply device is mounted on a high-pressure inert gas input pipe of the device for atomizing, spraying and depositing aluminum or aluminum alloy liquid. By virtue of the method, the high-pressure inert gas is taken as the flow carrying medium for spraying the tungsten powder and attaching the tungsten powder onto the surfaces of the aluminum or aluminum alloy micro-droplets, then the tungsten powder and the aluminum or aluminum alloy micro-droplets are solidified to prepare the tungsten powder reinforced aluminum matrix composite; the agglomeration of the tungsten powder can be effectively prevented; the tungsten powder reinforced aluminum matrix composite with uniformly distributed tungsten powder is prepared.

Description

technical field

[0001] The invention belongs to the technical field of aluminum-based composite material preparation, and in particular relates to a preparation method and device for a tungsten powder-reinforced aluminum-based composite material. Background technique

[0002] Particle-reinforced aluminum matrix composites are metal matrix composites formed by adding particle-reinforced phases to aluminum or aluminum alloys. Particle-reinforced aluminum-based composites have the advantages of light weight, low density, good plasticity of aluminum and aluminum alloys, and high strength, high temperature resistance, and wear resistance of the particle-reinforced phase. As a high-performance structural material, particle-reinforced aluminum matrix composites are widely used in the manufacture of spacecraft structural parts, aircraft parts, auto parts, microwave circuit plug-ins, navigation system precision parts, turbocharged propellers, electronic packaging devices, etc. At pr...
