Alumina ceramic brazing.

Alumina ceramic was brazed to different metals such as ti ni nb fe and aisi 304 stainless steel. Based brazing filler metals to braze 94 alumina ceramic to fe 29ni 17co alloy a controlled expansion alloy often used when brazing to ceramics. Passive al 2 o 3 brazing of ceramic and metal the most widely used method for brazing of ceramic and metal is passive al2o3 brazing with an agcu28 eutectic solder having a melting point of 779 c. The application of ultrasonic waves enhanced the wetting of alumina by zn al filler alloy.

Refractory structure ceramic industrial ceramic brazing material. A novel method of brazing is developed where resistance heating of c p titanium is done inside a thermal evaporator using a ta heating electrode. Alumina systems distinguishes between three types of soldering as a connection technique. Micro ceramics provides alumina parts for a wide range of applications including semiconductors optoelectronics aviation and communication.

One of the many promising applications of metal ceramic joining is in biomedical implantable devices. Brazing is a liquid phase process that is particularly well suited to preparing joints and seals and is an established technique for the joining of ceramics. The alumina ceramic chambers to be produced have the following characteristics to meet the rcs vacuum requirements. The brazing process can be readily adapted to the mass production of components such as those used in the electronics and automotive industries.

Prerequisite here is always a metallization of the ceramic. This work is focused on vacuum brazing of c p titanium to 96 alumina ceramic using pure gold as the filler metal. Alumina also is a good material for joining to metal or other ceramics using metalizing and brazing techniques. All of the brazed samples shown in table 1 as well as those shown in the subsequent tables tables 2 4 passed a helium mass spec trometer leak detection test leak rate.
