Silicon carbide ceramic connecting method and silicon carbide heat exchange tube manufactured through silicon carbide ceramic connecting method
The invention belongs to the technical field of ceramic connection, and discloses a silicon carbide ceramic connection method and a silicon carbide heat exchange tube manufactured through the silicon carbide ceramic connection method. The silicon carbide ceramic connection method comprises the following steps: (1) preparing glass powder, and pressing the glass powder into a green block; (2) laser micro-texture treatment is conducted on the surfaces to be connected of the two silicon carbide parts; (3) the green block is placed between two silicon carbide parts with the surfaces to be connected subjected to laser micro-texture treatment, and an assembly to be connected is obtained; and (4) the to-be-welded part of the to-be-connected assembly is put into a heating furnace for welding treatment, and the silicon carbide ceramic connecting piece is obtained after cooling. The obtained silicon carbide connecting piece joint has good corrosion resistance and high-temperature self-sealing performance, and keeps high mechanical strength at 800 DEG C.
本发明属于陶瓷连接技术领域，公开了一种碳化硅陶瓷连接方法及其制成的碳化硅换热管。碳化硅陶瓷连接步骤包括：(1)制备玻璃粉体，并压制成生坯块体；(2)对两件碳化硅零件的待连接表面做激光微织构处理；(3)将生坯块体放置于两件待连接表面经激光微织构处理后的碳化硅零件中间，得到待连接组件；(4)将待连接组件的待焊接部位放入加热炉中进行焊接处理，冷却后得到碳化硅陶瓷连接件。所得碳化硅连接件接头具有良好的耐腐蚀性能和高温自密封性能，在800℃下保留较高的机械强度。
