| Abstract: | Carbon fibers were coated with tungsten carbide film by metal organic chemical vapor deposition method with a precursor of hexacarbonyl tungsten,and the processing parameters of depositing tungsten carbide onto carbon fiber were studied.The results show that the surface of carbon fibers is covered with a dense and regular tungsten carbide film which is deposited at temperature of 400℃with holding time of 15min.The thickness of as-deposited film is about 0.4μm,and the phase of film is WC1-x.There is good adhesion between the coated film and carbon fiber.The DTA analysis results indicate that the thermal anti-oxidization properties of carbon fiber composites are improved significantly. |
| Keywords: | carbon fiber metal organic chemical vapor deposition(MOCVD) tungsten carbide hexacarbonyl tungsten |
