Silicon carbide composite cladding connecting method and silicon carbide composite cladding
The invention discloses a silicon carbide composite cladding connecting method and a silicon carbide composite cladding, and the connecting method comprises the following steps: S1, machining an end plug, and forming a T-shaped end at the first end of the end plug; s2, the T-shaped end of the end plug is matched with the inner-layer core mold; s3, arranging silicon carbide fibers on the outer surfaces of the inner-layer core mold and the end plugs to form a silicon carbide braid layer; s4, performing carbon deposition on the silicon carbide braid layer to form an interface layer on the surface of the silicon carbide fiber; s5, carrying out densification treatment on the silicon carbide braid layer; and S6, depositing a silicon carbide outer layer on the densified silicon carbide braid layer. According to the method, the inner core mold and the end plug are fixed preferentially, then the silicon carbide braid layer is arranged on the outer side and densified, and finally the cladding pipe is formed by matching with the silicon carbide outer layer, so that the connection reliability of the end plug and the cladding is improved, the air tightness and the corrosion resistance are improved, and the operation safety of the nuclear power station is improved.
本发明公开了一种碳化硅复合包壳连接方法及碳化硅复合包壳，连接方法包括以下步骤：S1、加工端塞，所述端塞的第一端形成T形端；S2、将所述端塞的T形端与内层芯模配合；S3、将碳化硅纤维设置在所述内层芯模和所述端塞的外表面，形成碳化硅编织层；S4、对所述碳化硅编织层进行碳沉积，以在碳化硅纤维表面形成界面层；S5、对所述碳化硅编织层进行致密化处理；S6、在致密化后的所述碳化硅编织层上沉积碳化硅外层。本发明通过优先进行内层芯模与端塞的固定，再在外侧设置碳化硅编织层及致密化，最后配合碳化硅外层以形成包壳管，该种方式有利于提高端塞与包壳连接的可靠性，提高气密性及耐腐蚀性，从而提高核电站运行的安全性。
