PDF CVD Production Systems for Industrial Coatings
Chemical vapor infiltration (CVI) is a chemical vapor deposition (CVD) process that is performed at low pressures to allow for coating of the internal surfaces of a porous material. Using heat and low pressure, precursor vapors penetrate the pores / fibers of the material and react to form a conformal coating on the internal surfaces.

Chemical Vapor Deposition (CVD) is an atmosphere controlled process conducted at elevated temperatures (~1925° F) in a CVD reactor. During this process, thin-film coatings are formed as the result of reactions between various gaseous phases and the heated surface of substrates within the CVD reactor.

CVD Coating Chemical vapour deposition or CVD is a generic name for a group of processes that involve depositing a solid material from a gaseous phase and is similar in some respects to physical vapour deposition (PVD).PVD differs in that the precursors are solid, with the material to be deposited being vaporised from a solid target and deposited onto the substrate.

The superior bond strength of Ti-Coating CVD coatings is achieved by means of the chemical reaction that takes place between the coating compound and the surface of the heated substrate material. The strong bond, combined with the ability to create multiple layers with relative ease, makes the CVD process the workhorse of coating technology.
