CVD Equipment Corporation’s CVI 200™ allows for the infiltration of CMC preforms as well as the deposition of ultra-high temperature ceramic (UHTC) coatings. UHTC coatings are a category of materials exhibiting some of the highest temperature melting points. The materials are designed to operate in extreme environments where conventional monolithic ceramics and metals would fail due to extreme heat and oxidation conditions, and have many applications including aerospace and defense, and hypersonics.

The CVI 200™ can be configured to enable the deposition of UHTC coatings onto C/C and SiC/SiC CMCs with a variety of precursors materials, including silicon carbide (SiC), silicon nitride (Si₃N₄), boron nitride (BN), silicon boron nitride (SiBN), boron carbide (B₄C), pyrolytic carbon (C), halfnium carbide (HfC), hafnium diboride (HfB₂), zirconium carbide (ZrC), and zirconium diboride (ZrB₂).

Precise control of temperature, atmospheric pressure, gas flows, exhaust stream, and substrate rotation to produce coatings with uniform thickness.

powered by CVDWinPrC™

Powered by our CVDWinPrC™ process control software, the systems automatically log data and graphically show time-dependent values of user-selected parameters. CVDWinPrC™ also allows users to load preprogrammed recipes, modify, check, and create new recipes, and view real-time or saved process data.

Safety Protocols

The systems have application configured safety protocols embedded into relay logic, PLC, and CVDWinPrC™ software.
