光纤光栅传感器金属化保护及钎焊嵌入42CrMo钢

Fiber bragg grating sensor metallization and embedding into 42CrMo steel by soldering

    摘要
  • 摘要: 针对光纤光栅传感器保护方面及向金属中封装嵌入方面现存的问题,采用化学镀和电镀结合的方法对光纤光栅传感器进行镀镍金属化保护,随后用钎焊的方法将传感器嵌入42CrMo结构钢中,从而获得智能金属结构。结果表明,镀层与传感器结合界面无缺陷,镀镍金属化使光纤获得了良好的保护,为后续钎焊嵌入金属做好了准备;钎焊对传感器影响较小;对钎焊后获得的智能结构进行了温度监测,表明传感器的灵敏度提高1倍,温度与波长变化成线性关系。

     

    Abstract: To solve the problem of fiber bragg grating(FBG) sensor protection and embedding in metal, FBG was protected with nickel coating by using chemical and electric plating method.The metallized FBG was then embedded into 42CrMo steel successfully and a smart metal part was acquired.Experiment results show FBG was protected successfully with the nickel layer, and there were no defects at the FBG nickel layer interface.The heat did not wreak the FBG during soldering process.Temperature monitoring results show the temperature sensitivity of FBG was increased twofold after metallization and soldering, and the temperature change was linear with reflection wavelength.
