摘要

高温光纤耐温和耐腐蚀主要取决于表面的涂覆层，为了测试可以耐受高温氟盐腐蚀的光纤，采用镀金光纤进行实验。将镀金光纤分别置于600℃及650℃熔融状态的氟盐中进行实验检测，经过在扫描电镜下观察分析，光纤镀金层完整，未见明显腐蚀迹象，可以考虑将其应用在熔盐堆上进行短时温度测量。

Abstract

Background

The property of temperature-and corrosion-resistance of high temperature optical fiber depends on the coating layer on the surface.

Purpose

This study aims to find an optical fiber withstanding high temperature fluoride salt corrosion.

Methods

Gold-plated optical fiber was selected for experimental test in the fluoride salt of the molten state at temperatures of 600℃ and 650℃. The samples were taken out after 24 h steeped in the high temperature molten salt

and then observed under the scanning electron microscope (SEM).

Results

The SEM images of gold plating layer of the optical fiber show that the surface of the fiber remained intact

and there is no obvious sign of corrosion.

Conclusion

It can be applied to the molten salt reactor for the short-time temperature measurement.
