METHOD OF MAKING HIGH-STRENGTH BRAZED JOINTS |
摘要 |
The invention relates to a method of making high-strength brazed joints in metal/ceramic and ceramic/ceramic composite materials. The brazing surface of the ceramic part is structured prior to brazing by introducing bores having an average diameter in the range of 50 mu m-500 mu m and a depth in the range of 100 mu m-2 mm. Preferably, the structuring is effected by laser working. Brazing is subsequently carried out in a conventional manner. The resulting joint displays increased strength characteristics and resistance to thermal stresses over joints produced by conventional methods.
