Surface Modification of Quartz Fiber by Aqueous Plasma Electrolysis

The mechanical properties of quartz and ceramic fiber are easily destroyed at high temperature. There are many process methods for continuous fiber surface treatment, commonly used in a chemical vapor deposition method and sol gel method. In this work, a method of preparing surface coating is proposed to protect the mechanical properties of fiber at high temperature, at the same time to achieve high efficiency, low cost, and to meet the requirements of Engineering production. Treatment of quartz and ceramic fibers in a continuous liquid equal plasma, plasma bombardment of the fibers is carried out, in order to achieve the purpose of preparation of coatings. After coating the surface of the quartz fiber, the ceramic coating is coated by the liquid plasma process, and the breaking strength is tested after the high temperature treatment.
