摘　　要：为了用金属直接固化代替目前的环氧粘接技术,从而实现光纤光栅传感器的无胶粘接,提出了一种无需粗化的光纤光栅传感器表面金属化工艺方法,并通过化学镀镍磷(Ni-P)合金,实现了光纤传感器的金属化封装。采用扫描电子显微镜、能谱仪、X射线衍射仪及热振试验分别对涂层的表面形貌、成分、结构和结合力进行了检测和分析,结果表明,制备所得涂层表面光滑、平整且致密;同时,通过镀膜光纤光栅传感器件与金属构件的实际键合试验,证明其结合力强、力学性能良好,能满足光纤光栅传感器的使用要求。In order to protect the system of fiber Bragg grating（FBG） and keep its sensing performance on a high score,an adhesive-free bond which is considered as the alternative for epoxy adhesive technology is demanded.An electroless Ni-P plating process without coarsing for fiber Bragg grating was presented.With this plating method,the FBG was coated with a metal clad of Ni-P.By Scanning Electron Microscope（SEM）,Energy Dispersive Spectrometer（EDS）,X-ray diffraction（XRD） and Temperature vibration tests,the composition,structure and adhesion force of the plating coatings were analyzed.And the results indicate that the coating is smooth,flat and compact.The solder ability of Ni-P clad was tested by welding the FBG into metal components,and the results reveal that the coating films can meet the requirements of an adhesive-free bond.
