Embodiment 1
[0041] This embodiment provides a welding method for alumina ceramics and metal molybdenum, the flow process is as follows figure 1 As shown, the specific steps are as follows:
[0042] (1) Alumina ceramic rod 2, molybdenum column 1 (purity is 99.99%) and molybdenum sheet 3 (purity is 99.99%, thickness is 0.25mm) is cleaned with concentration of 98% acetone, wherein the end face of molybdenum column is provided with hole Groove, a through hole is opened on the molybdenum sheet corresponding to the hole groove of the molybdenum column;
[0043] (2) Insert six cleaned alumina ceramic rods 2 into the grooves of the molybdenum column 1, and then place the molybdenum sheet 3 on the molybdenum column 2 on the side where the alumina ceramic rod 2 is inserted, so that the alumina ceramic rod 2 through the through hole on the molybdenum sheet;
[0044] (3) adding an adhesive 4 at the position where the alumina ceramic rod 2 is connected to the molybdenum column 1 and the molybdenum s...
Embodiment 2
[0048] Except that the thickness of the molybdenum sheet is 0.2 mm, the temperature of the vacuum furnace in step (4) is 1300 ° C, and the heating pressure is 4 × 10 - 4 Pa, the heating temperature is 1000°C, heat treatment for 15min, the prepared workpiece is stored in a nitrogen cabinet, other steps and material consumption are the same as those in Example 1, and the joint strength of the prepared workpiece is not low at the welding joint at 100MPa.
Embodiment 3
