Preparation method of boron carbide composite material
The invention relates to a preparation method of a boron carbide composite material. The preparation method comprises the following steps of: pretreating boron carbide powder; carrying out compression moulding on the pretreated boron carbide powder; presintering a boron carbide skeleton; carrying out pressureless infiltration treatment on the presintered boron carbide skeleton and an infiltration metal; carrying out heat treatment on an initial boron carbide composite material blank which is subjected to pressureless infiltration to obtain the high-purity boron carbide composite material. The method disclosed by the invention is simple, low in cost and low in energy consumption; in addition, the boron carbide composite material prepared through the method has the advantages of large size, near-net shape, high hardness and the like.
