一种Al2O3陶瓷与钛环的扩散连接方法
摘要：
本发明涉及一种Al2O3陶瓷和钛环的扩散连接方法，将待连接Al2O3陶瓷和钛环放入丙酮中超声清洗5min~10min；将钛环的待连接面朝下置于Al2O3陶瓷薄片的待连接面上，装配成Al2O3陶瓷/钛环的装配件；将得到的装配件放置在真空加热炉中，施加压力为1MPa~15MPa，当真空度达到(1.3~2.0)×10-3Pa时，通电加热，控制升温速度为5℃/min~15℃/min，升温至900~1000℃，然后保温60min~120min，再控制冷却速度为3℃/min~10℃/min，冷却至300℃，然后随炉冷却，即完成Al2O3陶瓷与钛环的扩散连接。本发明所得Al2O3陶瓷/钛环接头组织致密，具有较高强度，可应用于人造视网膜结构。
摘要（英）：

The invention relates to an Al2O3 ceramic and titanium ring diffusion connection method. The method comprises putting an Al2O3 ceramic and a titanium ring to be connected into acetone, carrying out ultrasonic cleaning for 5-10min, putting the titanium ring of which the surface to be connected faces down on a surface of the Al2O3 ceramic slice to be connected, assembling the Al2O3 ceramic slice and the titanium ring to obtain an Al2O3 ceramic/titanium ring assembly, putting the assembly in a vacuum heating furnace, applying pressure until 1-15MPa, when a degree of vacuum is (1.3-2.0)*10<-3> Pa, carrying out electrical heating at a heating rate of 5-15 DEG C/min until a temperature of 900-1000 DEG C, carrying out thermal insulation for 60-120min, cooling the assembly to a temperature of 300 DEG C at a cooling rate of 3-10 DEG C/min, and carrying out furnace cooling so that Al2O3 ceramic and titanium ring diffusion connection is realized. The Al2O3 ceramic/titanium ring joint has a compact structure and high strength and can be used for an artificial retina structure.
