Preparation and Oxidation Behavior of SiO2/SiC Coating on Braided Carbon Fiber
People pay more attention to improving the high-temperature oxidation resistance of carbon fiber in aerobic environment. In this study, we proposed a novel method to overcome these critical problems. SiO2/SiC coating was successfully prepared on braided carbon fiber surface by electrolytic plasma spraying. The scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) results showed the changes of surface morphology and surface composition by depositing the coatings, respectively. The energy dispersive spectroscopy (EDS) was employed for identifying the elemental composition of the deposited coating. Thermogravimetric (TG) and differential thermal analysis (DTA) results revealed that the high-temperature oxidation stability of the coated braided carbon fiber was significantly improved.
