Aluminum nitride ceramic surface metallization method
The invention relates to a method for metallizing an aluminum nitride ceramic surface. The method comprises the following steps: pretreating the aluminum nitride ceramic surface; the AgCuTi active brazing filler metal foil is prepared from, by mass, 20%-40% of Ag-Cu-1%-8% of Ti; paving an AgCuTi brazing filler metal foil which is subjected to destressing treatment and has the same shape and size as the surface to be metallized on the surface to be metallized of the pretreated aluminum nitride ceramic; and putting the aluminum nitride ceramic on the lower part and the AgCuTi brazing filler metal foil on the upper part into a vacuum brazing furnace, keeping the temperature at 840-900 DEG C for more than 10 minutes, cooling to below 400 DEG C at a cooling rate not higher than 5 DEG C/min after keeping the temperature, cooling to room temperature along with the furnace, and discharging from the furnace. According to the method, an AgCuTi active brazing filler metal metallization method is utilized, conventional active brazing filler metal for ceramic brazing is ingeniously utilized, and the method is simple, easy to implement, low in cost and particularly suitable for large-piece, single-piece or small-batch ceramic metallization production.
本发明涉及一种氮化铝陶瓷表面金属化的方法，包括：氮化铝陶瓷表面预处理；质量百分数为Ag‑20～40％Cu‑1～8％Ti的AgCuTi活性钎料箔去应力处理；在预处理后的氮化铝陶瓷的待金属化表面平铺形状及尺寸与所述待金属化表面相同的去应力处理后的AgCuTi钎料箔；将氮化铝陶瓷在下、AgCuTi钎料箔在上放入真空钎焊炉内，保温温度为840℃～900℃，保温时间为10min以上，保温结束后以不高于5℃/min的冷却速率冷却至400℃以下，再随炉冷却至室温后出炉。本发明方法利用AgCuTi活性钎料金属化法，巧妙利用常规陶瓷钎焊用活性钎料，简单易行，成本低，特别适合大件、单件或小批量陶瓷金属化生产。
