Pipeline gasket and preparation method thereof

The invention discloses a pipeline gasket and a preparation method thereof, and belongs to the technical field of pipeline welding. The method comprises the following steps: firstly processing a metal matrix, then processing a groove in the surface of the metal matrix, then spraying a nano ceramic material on the surface of the groove, and finally forming a ceramic coating on the surface of the groove. It can be seen that the pipeline gasket prepared through the method is composed of the metal matrix and the ceramic coating, compared with a ceramic material, metal is high in heat dissipation performance, resistant to high temperature and not prone to being affected by welding high temperature, and therefore the welding quality can be improved by combining the metal material and the ceramic material to prepare the pipeline gasket. 本申请公开了一种管道衬垫及其制备方法，属于管道焊接技术领域。该方法先加工金属基体，然后在金属基体表面加工凹槽，再在凹槽表面喷涂纳米陶瓷材料，最终在凹槽表面形成陶瓷涂层。可见，该方法制备的管道衬垫由金属基体和陶瓷涂层组成，相较于陶瓷材料，金属的散热性强，且耐高温，不易受焊接高温影响，因此，将金属材料与陶瓷材料相结合来制备管道衬垫，可以提高焊接质量。
