Product Description

Graphite components for PVD and CVD coating

Graphite and components made of graphite are utilized at creating thin layers of TiC and TiN by means of PVD and CVD processes.
Due to high thermal, chemical and mechanical resistance of graphite, the following items are utilized at the abovementioned processes.

What is CVD?

CVD stands for "chemical vapor deposition". This is an effective process for coating components via a thermally induced chemical reaction.

Advantages of CVD

CVD coatings offer outstanding adhesion, even under extreme operating conditions. This results in homogeneous components without weak spots. Create a technical edge with a CVD coating and improve the quality of your products. We produce high-quality, customized components made in graphite, CFC an insulation mateirals  for your coating system.
