一、序言 可伐合金(4J29)与硬玻璃封接时,在封接界面的玻璃内侧常常产生封接气泡,气泡达到一定数量,或成密集的串状时就会破坏封接界面的气密性,致使封接元件报废。有人对气泡内的气体进行分析,认为主要是CO和CO_2气泡。当金属和玻璃在一定温度下封接时,金属中的炭和氧反应生成上述气泡,如何减少和避免封接气泡的产生,人们做了大量工作。有效的主要办法之一,是可伐合金在封接前进行高温湿氢处理。也即成型的零件经过去油,酸
First, the preface Kovar (4J29) and hard glass sealing, the sealing surface of the glass often have sealed bubbles inside the bubble to reach a certain number, or into a string of dense will destroy the sealing interface airtight Sexual, resulting in sealing components scrapped. Some people analyze the gas inside the bubble, that is mainly CO and CO 2 bubbles. When metal and glass are sealed at a certain temperature, the carbon and oxygen in the metal react to form the above-mentioned bubbles. Much work has been done on how to reduce and avoid the generation of sealed bubbles. One of the most effective ways to do this is to use Kovar alloy for high temperature wet hydrogen treatment prior to sealing. That is shaped parts after degreasing, acid
