Vacuum induction chemical vapor deposition furnace

The vacuum induction chemical vapor deposition furnace using medium frequency induction heats the graphite crucible which placed in the induction coil under vacuum or protective atmosphere, and can also be heated by resistance, and the prepared carbon-carbon composite material is placed in the graphite crucible. The crucible is heated to a prescribed temperature at a certain temperature, then inlet diluted hydrocarbon gas. The carbon-containing active gene in the gas is decomposed and deposited on the surface of the material. The composite material thus prepared will greatly increase the wear resistance. This equipment is suitable for the preparation of composite materials by chemical vapor deposition, or as sintering of cemented carbide products. Carbon-carbon composite is an advanced composite material of carbon fiber reinforced carbon matrix, featuring low density, high specific strength, high temperature resistance (3000 ° C), and excellent friction and wear properties. In the early days, the carbon-carbon composite products developed through test methods were mainly used in the aerospace field, such as military aircraft brake discs, rocket engine nozzles, combustion chambers, nose cones and other key components. At present, carbon-carbon composite materials are widely used in modern transportation, large-scale manufacturing, national large-scale nuclear energy engineering, modern national defense construction, high-temperature thermal protection, semiconductor industry, hot-pressing molds, etc,due to their excellent performance.

The key technology for the preparation of carbon-carbon composites is the densification of carbon   fiber preforms - the CVI process. The carbon-carbon composite chemical vapor deposition furnace is a special equipment for the CVI process. In view of the wide application fields and broad
market prospects of carbon-carbon composites, our company has developed a large-scale carbon-carbon composite chemical vapor deposition furnace, which is mainly used for chemical vapor deposition of large carbon-carbon products.Also the furnace could be used for vacuum carbonization of the whole process.
