They are designed to enable controlled deposition of materials on the surface of the processed materials.   Purification furnaces using gases such as hydrogen chloride (HCl) are used to purify graphite materials.  SECO/WARWICK has a long history of manufacturing graphite disc infiltration furnaces for the aerospace industry dating back to the 1980s. The experience gained over the decades means that as a business partner, we have invaluable knowledge, competence and skills to successfully meet the highest demands and expectations of our partners. 

• CVI (Chemical Vapor Infiltration), CVD (Chemical Vapor Deposition) and graphite purification devices are tools used in materials science to produce, process, and purify carbon materials such as graphite.  

• CVI equipment consists of a reactor or reaction chamber in which chemical and temperature parameters are controlled to deposit layers of carbon on a substrate. 

CVI is a process in which carbon material (usually in the form of a porous structure) is saturated or impregnated with carbon materials in the gas phase. The CVI process uses carbonaceous gases such as methane or acetylene, which react in the reactor to form carbon deposits on the substrate surface.  CVI technology is used in the production of carbon brake discs for high-performance, sports, electric and luxury cars. In the case of the brake disc production, the process enables the creation of a structure with exceptional strength and low weight, which is crucial for effective braking. By precisely managing this process, brake discs produced using CVI have excellent high temperature resistance, minimal wear, and excellent friction properties, ensuring safe and efficient vehicle braking. 

• CVD equipment contains a reaction chamber where parameters such as temperature, pressure and chemical composition of the process gas are controlled. 

CVD is a technique for producing coatings on the substrate surfaces through chemical reactions in the gas phase.   The chemical deposition process (CVD) is a technique used, for example, to produce protective coatings (tool drilling). The CVD furnace creates protective layers on tools, increasing their durability, strength, and efficiency during processing. In the CVD process, chemical reactions allow layers to be deposited on the tool surface, improving its properties. These coatings provide better resistance to abrasion, high temperatures and corrosive environments, which translates into extended tool life and increased efficiency during industrial production.
