一种钨粉增强铝基复合材料的制备方法及装置
摘要：
一种钨粉增强铝基复合材料的制备方法及装置，其方法是：在铝或铝合金液雾化喷射沉积装置的高压惰性气体输入管上安装钨粉定量供应装置，利用高压惰性气体为载流介质，将钨粉喷射到雾化形成的铝或铝合金微液滴的表面，而使钨粉分散粘附在铝或铝合金微液滴的表面，然后一起喷射沉积到基板上，凝固后得到钨粉增强铝基复合材料。其装置是：包括铝或铝合金液雾化喷射沉积装置，该铝或铝合金液雾化喷射沉积装置的高压惰性气体输入管上安装有钨粉定量供应装置。本发明由于利用高压惰性气体为载流介质将钨粉喷射粘附在铝或铝合金微液滴的表面，然后一起沉积凝固得到钨粉增强铝基复合材料，可有效防止钨粉发生团聚，得到钨粉均匀分布的钨粉增强铝基复合材料。
摘要（英）：

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.
