With the quartz fiber as the matrix materials, the copper-plating quartz optical fiber is produced by electroless nickel-plating and copper electroplating. The influences of pretreatment roughening time activa⁃tion time, activation temperature on bond strength and continuity of nickel-phosphorus alloy coatings are studied with colloidal palladium activation. The results indicate that only in which condition at the room temperature, roughening time is 2-10 min, activation temperature is 30-40 ℃ , activation time is 20 min, the continuous, dense, uniform, bright and highly cohesive nickel-plated underlying on the surface of the quartz fiber can be pre⁃pared successfully. Copper-plating optical fiber with high adhesion, low resistivity and good welding can be ob⁃tained by electroplating copper on the electroless Nickel-plating quartz optical fiber. By testing the temperature sensing performance of the copper electroplating optical fiber, it is found that the temperature sensitivity coeffi⁃cient of the copper electroplating optical fiber is 1.7 times than that of ordinary optical fiber, that is, enhanced sen⁃sitivity effect of temperature is obvious.% 以石英光纤光栅为基体材料,采用化学镀镍和电镀铜相结合的工艺制备金属化光纤光栅.采用胶体钯活化法进行光纤光栅的活化处理,通过研究预处理粗化时间、活化时间与活化温度关键参数等对镍磷合金镀层结合强度和连续性等性能的影响,确定了最佳工艺条件：室温下粗化时间2~10 min,活化温度30~40℃,活化时间20 min,在石英光纤表面得到了连续、致密、均匀、光亮和附着力强的镍镀底层.采用电镀法在镀镍光纤光栅上继续镀铜,得到了具有高附着力、低电阻和良好焊接性能的金属化光纤光栅.对镀铜光纤进行温度性能测试,发现镀铜处理后的光纤光栅温度灵敏系数是普通光纤光栅的1.7倍.
