Influence of Coating Temperature on Online Preparation and Tensile Properties of Zn Coated Silica Fiber

Abstract

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
