Surface acoustic wave ultra-high-temperature strain sensor resistant to thermal expansion mismatch and high-temperature aging
The invention discloses a surface acoustic wave ultra-high temperature strain sensor resistant to thermal expansion mismatch and high temperature aging, the sensor comprises a silicic acid gallium lanthanum surface acoustic wave resonator and a ceramic spraying package, and strain is transmitted through the ceramic spraying package. For a measured object, thermal expansion mismatch between the sensor and the nickel-based high-temperature alloy at high temperature can be reduced through ceramic spraying packaging. In addition, ceramic spraying packaging has high toughness and high-temperature aging resistance, can bear huge strain caused by thermal expansion of the nickel-based high-temperature alloy, and keeps strain transmission to the sensor at the same time. The surface acoustic wave ultra-high-temperature strain sensor can adapt to multiple repeated strain tests at the temperature of 800 DEG C or above.
本发明公开一种抗热膨胀失配和高温老化的声表面波超高温应变传感器，该传感器包括硅酸镓镧声表面波谐振器和陶瓷喷涂封装，通过陶瓷喷涂封装来传递应变。对于被测物体，陶瓷喷涂封装可减轻高温下传感器与镍基高温合金之间的热膨胀失配。此外，陶瓷喷涂封装具有较强的韧性和抗高温老化能力，能承受镍基高温合金热膨胀引起的巨大应变，同时保持对传感器的应变传递。该声表面波超高温应变传感器能够适应800℃以上的多次重复应变测试。
