摘要/Abstract

摘要： 本文通过熔融金属法在线制备镀锌石英光纤,并探究涂覆温度对镀锌石英光纤表面质量和力学性能的影响。通过图像处理软件统计镀层包覆率,通过扫描电子显微镜、偏反光显微镜和激光共聚焦显微镜分别测量镀层厚度、晶粒尺寸和粗糙度,发现随着涂覆温度的升高,镀层包覆率和镀层厚度均减小;镀层凝固时间延长,晶粒尺寸增大;镀层粗糙度逐渐增大。通过抗拉试验机测量镀锌石英光纤的最大拉断力,与裸光纤相比,提升了139%。

Abstract: In this paper, Zn coated silica fiber was prepared online by molten metal method, and the influence of coating temperature on the surface quality and mechanical properties of Zn coated silica fiber was explored. The coating coverage rate was calculated using image processing software. The coating thickness, grain size, and roughness were measured using scanning electron microscopy, polarizing microscopy, and laser confocal microscopy, respectively. It is found that as the coating temperature increases, the coating coverage rate and coating thickness decrease, the solidification time of coating is prolonged, the grain size increases, and the roughness of coating gradually increases. The breaking force was measured by tensile testing machine. The maximum breaking force of Zn coated silica fiber increases by 139% compared with bare fiber.

Key words: Zn coated silica fiber, molten metal method, coating temperature, coating coverage rate, interface combination, tensile property
