MAX phase ceramic material welding method
The invention provides an MAX phase ceramic material welding method. In the provided welding method, the ends of two MAX phase ceramic materials to be welded are respectively connected to an upper electrode and a lower electrode, the welding surfaces are processed and then contacted with each other, then the ceramic materials, electrodes, and a power supply form a closed loop, joule heat is generated by the current on the touch surfaces, the temperature of the touch surface is rapidly raised, thus the MAX phase ceramic material of the touch surface is activated and diffused, and the welding is achieved. In the conventional welding method, a middle transition layer is used, and the middle transition layer is diffused at a high temperature under the combined actions of temperature-pressure-temperature maintaining so as to achieve the welding. Compared with the conventional welding method, the provided welding method has the following advantages: (1) the method is simple and practical; (2) a middle transition layer is not needed; (3) the welding period is short; (4) no welding silt or interface on the surface of welded material, and the ceramic materials are perfectly integrated together; (5) the welding method has a very good application prospect.
