Polycrystal B4C-SiC double-layer composite material and preparation method thereof
The invention provides a preparation method of a B4C-SiC double-layer composite material, and the B4C-SiC double-layer composite material. The preparation method of the B4C-SiC double-layer composite material comprises the steps that a B4C powdery material and a SiC sandy material serve as raw materials and are mixed and batched in a certain mode, and then the mixed and batched materials are subjected to press-fit forming and high-temperature calcination, wherein the addition ratio of the B4C powdery material to the SiC sandy material is 1: 1.5. The preparation method specifically comprises the steps of raw material primary treatment, mixing and batching, press-fit molding and high-temperature calcination, and in the mixing and batching process, the B4C powdery material and the SiC sandy material can be mixed according to a group A mixing mode or a group B mixing mode, then press-fit molding is performed, and high-temperature calcination is performed. According to the preparation method of the B4C-SiC double-layer composite material, the SiC sandy material is used as a main filling material, the B4C powdery material is used as a wrapping and bonding material, and batching is conducted according to the corresponding proportion to obtain the high-strength composite material.
本发明提供了一种B4C‑SiC双层复合材料的制备方法及B4C—SiC双层复合材料，本发明的B4C‑SiC双层复合材料的制备方法，以B4C粉状材料和SiC砂状材料为原料，并按一定的方式进行混合配料，然后将混合配料压合成型并高温煅烧，其中，B4C粉状材料和SiC砂状材料的添加比例为1:1.5，该制备方法具体包括原料初处理、混合配料、压合成型和高温煅烧，且在混合配料过程中，B4C粉状材料和SiC砂状材料可按照A组混合方式或B组混合方式进行混料，然后压合成型并进行高温煅烧。本发明的B4C‑SiC双层复合材料的制备方法以SiC砂状材料作为填充主要材料、B4C粉状材料作为包裹粘合材料，并按照对应比列进行制备，可以获得高强度的复合材料。
