SiC ceramic connection method and SiC ceramic connector
The invention provides a SiC ceramic connection method and a SiC ceramic connector, and the connection method comprises the following steps: firstly, mixing a ceramic precursor, an organic solvent, an inorganic filler and a catalyst, then rapidly stirring the mixture to obtain a precursor adhesive, secondly, smearing the precursor adhesive between the butt joint surfaces of two adjacent SiC ceramics, and finally, forming the SiC ceramic connector. The preparation method comprises the following steps: firstly, forming a sandwich connection structure, then, carrying out first heat treatment on the sandwich connection structure to enable a precursor adhesive to be completely crosslinked and cured to form a connection layer tightly connected between two adjacent SiC ceramics, and finally, completely wrapping the periphery of the connection layer with silicon particles, and carrying out second heat treatment on the connection layer to obtain the silicon-based composite material. The silicon particles in the molten state are made to permeate into pores of the connecting layer; according to the invention, the SiC inorganic filler is added into the precursor adhesive, and the fused silicon permeation treatment is carried out on the cured connecting layer to perfectly fill the pores of the connecting layer, so that the connecting layer is compact and firm.
本发明提供了一种SiC陶瓷的连接方法及SiC陶瓷连接体，连接方法包括以下步骤：首先将陶瓷前驱体、有机溶剂、无机填料以及催化剂混合后并快速搅拌，得到前驱体粘接剂，其次，将前驱体粘接剂涂抹于相邻两个SiC陶瓷的对接面之间，形成三明治连接结构，再次，对三明治连接结构进行第一次热处理，使前驱体粘接剂完全交联固化，形成紧密连接在相邻两个SiC陶瓷之间的连接层，最后，将硅颗粒完全包裹于连接层的四周，并对连接层进行第二次热处理，使熔融状态的硅颗粒渗透至连接层的孔隙内；本发明首先在前驱体粘接剂中添加了SiC无机填料，并对经过固化完成后的连接层进行熔融硅渗透处理，完美填充连接层的孔隙，使得连接层致密且牢固。
