| 摘 要： | 引 言石英光纤广泛应用于光通信、光传感等领域 ,利用它制作的光纤传感器可用来测量物体的应力和应变 .但在测量前应先将传感器牢固地固定在待测物体上 ,常用的固定方法是使用环氧树脂等胶黏剂 ,这种方法存在着致命的缺点 ,即胶黏剂与待测物体和光纤涂覆层之间、光纤芯层和光纤涂覆层之间会产生相对移动 ,使得测量的数据不能真实地反映待测物体的应力和应变[1,2 ] .因此 ,若能将石英光纤表面金属化 ,然后用锡焊的方法使光纤固定在 Receiveddate:2 0 待测物体上 ,这一难题将会完全解决 .光纤表面金属化有多种方法可以实现 ,常用的方法…

| Abstract: | Quartz optical fibers are of great significance in many fields. For example,they can be used to fabricate strain sensors and temperature sensors.If the surface of optical fibers is metal-coated by the electroless plating method, the measuring precision and stability of the optical fiber sensors can be improved remarkably, additionally the life-span of sensors can be prolonged.In this work, an electroless nickel-phosphor plating process for optical fibers was presented.The influences of the content of NaH2PO2•H2O, bath pH value and temperature and the plating deposition rate on the quality of the plating coatings were studied with orthogonal testing.The results indicated that the content of NaH2PO2•H2O was the key factor, which influenced the adhesion force of the plating coatings.The nickel-phosphor plating bath presented in this work possessed excellent stability and the plating deposition rate could be accelerated.Using the process described in this work, nickel-phosphor coatings with great brightness and high adhesion force can be prepared successfully.Optimum conditions were: NiSO4 30 g•L-1, NaH2PO2•H2O 20 g•L-1, C3H6O3 4 ml•L-1, Na2CO3 3 g•L-1, NH4Cl 4 g•L-1, saccharin 1 mg•L-1, temperature 84 ℃, pH 4.6. |
