Preparation method of aluminum silicon carbide composite material structural member
The invention provides a preparation method of an aluminum-silicon carbide composite material structural member, which comprises the following steps: uniformly dispersing powder of two kinds of slurry, a solvent, a dispersing agent and a binder respectively, and carrying out vacuum defoaming to obtain slurry A and slurry B. The powder of the slurry A comprises aluminum and/or aluminum alloy powder and silicon carbide powder, and the powder of the slurry B comprises aluminum and/or aluminum alloy powder and silicon carbide powder. The slurry powder B is aluminum and/or aluminum alloy powder; performing 3D modeling and printing to obtain a product green body with a sheath; curing the green body; carrying out two-stage presintering on the cured green body: carrying out first presintering at a first presintering temperature in a vacuum atmosphere, then raising the temperature to a second presintering temperature, and carrying out second presintering in a vacuum atmosphere; carrying out hot isostatic pressing sintering on the pre-sintered product; and removing a sheath of a product subjected to hot isostatic pressing sintering to obtain the aluminum silicon carbide composite material structural member. According to the invention, the aluminum silicon carbide composite material structural member with a complex structure can be manufactured, and the product is ensured to have very high density.
本发明提供了一种铝碳化硅复合材料结构件的制备方法，所述制备方法包括以下步骤：分别将两种浆料的粉料、溶剂、分散剂、粘结剂分散均匀，真空除泡后得到A浆料和B浆料，其中A浆料的粉料包括铝和/或铝合金粉与碳化硅粉，B浆料粉料为铝和/或铝合金粉；3D建模打印得到带包套的产品生坯；将生坯固化；固化的生坯进行两段预烧结：在第一预烧结温度，真空气氛下进行第一次预烧结，后升温至第二预烧结温度真空气氛下进行第二次预烧结；将预烧结的产物进行热等静压烧结；除去热等静压烧结后的产物的包套得到铝碳化硅复合材料结构件。本发明可以制造结构复杂的铝碳化硅复合材料结构件，且保证产品具有很高的致密度。
