摘要
温度在科研和生产中是一个十分重要的物理量,当前许多研究对象需要测量的是幅值高、变化快的瞬态高温.在高温测试中,光纤高温传感器具有独特的优势,在制作光纤高温传感器过程中镀膜技术是一个关键的环节.根据高温测试需要,选取了合适的镀膜材料,对氧化锌(ZnO)和氧化镁铝(MgAl 2 O 4 )的物理化学性质进行了介绍,同时根据材料特性选择了适合的镀膜方法,分别适用于黑体腔温度传感器的头部镀层和光纤光栅传感器表面镀膜,取得了良好的效果,达到了预期的目标.
Abstract
Temperature is a very important physical indicator in science research and production process,presently many researchers always need to measure the high amplitude,fast transient changes temperature.It has a unique advantage with fiber optic temperature sensor in high temperature measurement,so the coating technol-ogy is a key part of the fiber optic temperature sensor.An appropriate coating material was selected for high-tem-perature test,the physical and chemical properties of ZnO and MgAl2O4were also introduced.At the same time,according to the material properties,an appropriate coating method was chosen and used for the head coat-ing of blackbody cavity temperature sensor and the Surface coating of the FBG sensor.This technology is proved feasible and achieved the desired goals.
