Embodiment Construction

[0004] 1. Optical fiber surface pretreatment: Use 30% sodium hydroxide solution by volume to remove organic matter on the optical fiber surface, wash with deionized water, roughen in hydrofluoric acid and ammonium fluoride solution, then wash with distilled water, dry, and finally immerse for activation Optionally, use V(40%HF):V(H2SiF6):V(H2O) = 1:1:2 to weaken in the crude solution for 10 minutes and 20 minutes respectively.

[0005] 2. The plating solution is composed of nickel chloride hexahydrate 24g / L, sodium hypophosphite 10g / L, potassium borohydride 10g / L, ethylenediamine 24mL / L, cadmium sulfate 0.6mg / L, pH=13-14, temperature 90°C, perform electroless plating on the prepared optical fiber.

[0006] The cross-sectional morphology of the electroless plating surface was observed with a scanning electron microscope, and the composition of the coating was measured with an energy spectrometer, a plasma emission spectrometer, XRD and other equipment and various conventional a...

Abstract

The invention relates to a chemical plating method for a quartz fiber surface. The plating solution consists of 24g/L of nickel chloride hexahydrate, 10g/L of sodium hypophosphite, 10g/L of potassium borohydride, 24mL/L of ethylenediamine and 0.6mg/L of cadmium sulfate. Chemical plating is performed when the pH of the plating solution is equal to 13 to 14 and the temperature is 90 DEG C. Nickel-phosphorus-boron alloy is chemically plated on the quartz fiber surface to improve the hardness and the electric conductivity of the fiber.

Description

technical field [0001] The invention relates to a method for electroless plating on the surface of quartz optical fiber, in particular to a method for electroless plating nickel-phosphorus-boron alloy on the surface of quartz optical fiber. Background technique [0002] Compared with traditional cables, quartz optical fiber cables have the advantages of anti-electromagnetic interference, good confidentiality, anti-nuclear radiation, light weight, small size, and low price. In recent years, with the application of silica optical fibers, surface metallization has become a current research hotspot. It is convenient for the fiber grating to be embedded in the metal and firmly connected with it, which requires the metal on the surface of the fiber to have good welding performance and circuit performance. Conventionally, it is realized by nickel-phosphorus plating, but the surface hardness and conductivity of the optical fiber obtained by this method often cannot meet the higher r...
