摘要
ZrO_2陶瓷型氧传感器具有测量精度高、范围广以及可直接以电压(或电流)形式输出等特点,在新型核反应堆有着重要的应用前景。然而由于ZrO_2陶瓷材料本身的特点及应用环境的特殊性,有必要进行ZrO_2陶瓷本体或与金属的可靠性连接,实现优势互补。综述了核电领域ZrO_2陶瓷的连接特点及目前用于ZrO_2陶瓷的连接方法,探讨各个连接方法的特点,并指出未来ZrO_2陶瓷连接技术的发展方向。
With the high measurement accuracy,wide range and direct output in the form of voltage(or current),ZrO_2 ceramic oxygen sensor has an important application prospect in the new type nuclear reactors. However,due to the characteristics of ZrO_2 ceramic material and special application environment,it is necessary to carry out a reliable joining of ZrO_2 ceramic with itself or metals to realize the complementary advantages. The joining characteristics and present joining methods of ZrO_2 ceramics in the field of nuclear power are summarized. The characteristics of each joining method are discussed,and the development direction of ZrO_2 ceramic joining technology is pointed out.
