摘要
光纤光栅锈蚀传感器将光纤光栅传感技术优势应用于钢结构混凝土的耐久性长期监测。对于基于锈蚀敏感膜的光纤光栅锈蚀传感器而言,敏感膜的质量对传感器整体性能起着关键的作用。引入脉冲电镀方法制备Fe-C薄膜,通过薄膜厚度和质量测试、传感器锈蚀实验,优化了脉冲电镀制备参数,分析和比较了脉冲电镀与直流电镀的所制备薄膜的特点,以及所制备传感器的锈蚀行为和传感寿命。通过薄膜形貌、测定薄膜附着力等方法研究Fe-C锈蚀敏感膜性能,通过加速锈蚀实验分析比较各电镀时间得到的传感器锈蚀行为,从而得到最佳电镀时间参数,并且将其与直流电镀方法进行了全面的对比。对比实验表明,脉冲电镀方法得到的Fe-C薄膜的表面平整度和附着力,以及传感器的线性工作区间和传感寿命均优于直流电镀方法得到的薄膜和传感器。
This paper discussed pulse electroplating for Fe-C film deposition on fiber Bragg grating(FBG)corro-sion sensor.A series of characterization techniques are used to optimize the plating time and compare the film quality and sensor behaviors between pulse electroplated films with different plating time and direct-current(DC)electroplated film.The film morphology is studied by SEM9and the film adhesion is studied by scratch methods and quenching.The sensors are characterized by immersing into NaCl solution to accelerate the corro-sion experiments.The result shows that the film fabricated by pulse electroplating exhibits better smoothness and film adhesion than DC method does.And the optimized time for pulse electroplating is obtained.This paper will contribute to the fabrication and application of Fe-C film coated FBG corrosion sensor.
