Preparation and Characterization of SiC Coated Carbon Fiber(Ⅱ) |
| 초록 |
Carbon-based materials exhibit outstanding mechanical properties, particularly at high temperatures. Nevertheless, their prolonged use in oxidising environments is limited to temperatures lower than 500℃ because of gasification of carbon as carbon oxides. In this work, SiC coated carbon fiber was obtained, through the coating of preceramic polymer using various kinds of polycarbosilane onto carbon fiber by dip coating method and they were carried out in a furnace under an argon flow at 800~1400℃, held at high temperatures for 1h. SiC has the ability to form a SiO2 layer in an oxidizing atmosphere which fills the cracks of the layer and increase the diffusion barrier efficiency. The crystallinity of the coating was examined by X-ray diffraction (XRD). Morphology and chemical composition were examined by scanning electron microscopy (SEM) and energy dispersive spectroscopy(EDS). Oxidation tests were performed with a thermo gravimetric analyser (TGA) under dry air flow. |
