摘要:
针对金属镀层光纤制备工艺复杂且技术不成熟的现状，对石英光纤表面Ni-P金属镀层的制备工艺进行优化，并对优化后镀层的性能进行研究。采用无粗化的前处理工艺化学镀Ni-P金属镀层，利用SEM、EDS对镀层的微观组织进行表征，采用热震试验和拉伸试验对镀层的结合强度和抗拉强度进行测试，并通过红外热成像仪测试金属镀层光纤导光后的热管理能力。结果表明：优化后的前处理工艺为去除保护层时丙酮浸泡时间15 min以上，除油时NaOH溶液的浓度为30 g/L，浸泡时间大于15 min，敏化、活化温度均为35 ℃，时间10 min；光纤表面镀层晶粒分布均匀，大小均一，且与基体结合良好，光纤最大抗拉强度平均为2783 MPa，较裸光纤提升52.93%；通光后金属镀层光纤表面温度达100 ℃时，通过功率为5.74 W，且功率和工作温度还可继续增加，能够克服光纤表面温度升高易烧损的缺点。

Abstract:
In view of the complex and immature preparation process of metal coating fiber, the preparation technology of the metal coating on quartz fiber surface was optimized, and the properties of the optimized coating were studied. The pretreatment without coarsening was used in the experiment. SEM and EDS were used to characterize the microstructure of the coating. The bonding strength and tensile strength of the coated fiber were analyzed by thermal shock test and tensile test, and the thermal management capability of the metal coating fiber after passing light was tested by infrared thermal imager. The results show that: the optimized pretreatment process is as follows when removing the protective layer, the acetone will soak for more than 15 min; when removing oil, the concentration of NaOH solution will be 30 g/L; the soaking time should be more than 15 min. The sensitization and activation temperatures are 35 ℃ and 10 min. The coating grain on the surface of the optical fiber is evenly distributed and uniform in size, and it is well combined with the substrate. The maximum tensile strength is 2783 MPa on average, which is 52.93% higher than that of the bare optical fiber. After light transmission, the passing power reaches 5.74 W, when the tolerable temperature of the surface of the metal coating fiber reaches 100 ℃. The power and temperature can continue to increase, which can overcome the weakness of being easy to burn caused by the fiber surface temperature rising.
