Composite brazing filler metal, composite brazing filler metal soldering paste, preparation method of composite brazing filler metal soldering paste, aluminum nitride copper-clad ceramic and preparation method of aluminum nitride copper-clad ceramic
The invention discloses a composite brazing filler metal, a composite brazing filler metal soldering paste, a preparation method of the composite brazing filler metal soldering paste, an aluminum nitride copper-coated ceramic and a preparation method of the aluminum nitride copper-coated ceramic. The composite brazing filler metal comprises the following components in percentage by mass: 60-75 wt.% of silver, 20-30 wt.% of copper, 3.0-4.5 wt.% of titanium and 0.5-5.0 wt.% of aluminum nitride whiskers. The mass ratio of the silver to the copper to the titanium to the aluminum nitride whisker is (60-75): (20-30): (3.0-4.5): (0.5-5.0). Through the reinforcing and toughening effects of the aluminum nitride whiskers in the composite brazing filler metal and the pinning effect of the aluminum nitride whiskers between the aluminum nitride ceramic matrix and the metal copper, the residual stress at the brazed joint is reduced, and the physical performance and the mechanical performance of a brazed joint are remarkably improved; and the active element titanium is added, so that the activity of the composite brazing filler metal is improved, and the wettability of the composite brazing filler metal and an aluminum nitride ceramic matrix in the brazing process is improved.
本发明公开了一种复合钎料、复合钎料焊膏及制备方法、氮化铝覆铜陶瓷及制备方法，复合钎料包括以下质量百分比的组分：60wt.％～75wt.％的银、20wt.％～30wt.％的铜、3.0wt.％～4.5wt.％的钛和0.5wt.％～5.0wt.％的氮化铝晶须；银、铜、钛和氮化铝晶须的质量比为(60～75)：(20～30)：(3.0～4.5)：(0.5～5.0)。通过氮化铝晶须在复合钎料中的增强增韧作用，以及其在氮化铝陶瓷基体与金属铜之间的钉扎作用，减少钎焊接合处的残余应力，显著改善了钎焊接头的物理性能及力学性能；并且添加活性元素钛，增加了复合钎料活性，提高钎焊过程中复合钎料与氮化铝陶瓷基体的润湿性。
