研究了含Ａｌ、Ｔｉ和Ｚｒ等易氧化元素的合金连接陶瓷时的防氧化问题。结果表明，对于易变形的活性合金，施加适当的压力可防止在大气中直接连接陶瓷时连接区中合金的氧化；常规高真空环境下连接时，试样放于开有小长孔的夹具中也可以达到良好的防氧化效果。两种防氧化措施的原则是连接区或试样周围局部含氧量减至不影响活性合金与被连接材料的结合
The oxidation resistance of alloys with easily oxidizable elements such as Al, Ti and Zr was investigated. The results show that, for a deformable active alloy, suitable pressure is applied to prevent the oxidation of the alloy in the connection zone when the ceramic is directly connected to the atmosphere. When the connection is carried out in a conventional high-vacuum environment, the sample is placed in a jig having a small slot Can also achieve good anti-oxidation effect. The principle of the two kinds of anti-oxidation measures is that the local oxygen content in the connecting area or around the sample is reduced to not affect the combination of the active alloy and the connected material
