摘　　要：传统石英光纤的涂覆层一般是聚合物,在高温下极易发生降解,这种特性是光纤在高温环境下难以被应用的主要原因。金属材料比聚合物具有更好的耐高温特性,可以有效地保护光纤表面免受侵蚀,是耐高温光纤涂覆层材料的研究热点。本文分析和对比了五种主要的光纤表面金属化涂覆方法(真空蒸镀、溅射、电镀、化学镀、熔融涂覆)。结果表明,金属化光纤适宜在极端环境中进行信息的传输和传感,因为化学镀较为经济环保,已成为目前光纤小范围金属化的主要方法;熔融涂覆技术利用拉丝塔在线制备耐高温光纤,是金属化工业生产的主流选择。The coating layer of traditional silica optical fiber is generally polymer,which is prone to thermal aging at high temperatures.This characteristic is the main reason why optical fiber is difficult to be applied in a high temperature environment.Metal materials have better high temperature resistance than polymer,which can effectively protect the surface of the optical fiber from water vapor.It is a hot research topic of high temperature optical fiber coating materials.This paper analyzes and compares five main optical fiber surface metallization coating methods(vacuum evaporation,sputtering,electroplating,electroless plating,and freezing method).The results show that electroless plating is the main method for metallization of optical fiber devices due to its economical and environmentally friendly features.Melt coating technology is the mainstream choice of metal-chemical industry production.
