Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is usually a system whereby a substrate is exposed to a number of unstable precursors, which react and/or decompose around the substrate area to generate the specified thin movie.
Techniques while in the CVD Method:
Precursor introduction
Chemical response and movie formation
By-products elimination
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling typically utilized outside the house The us, especially in British English. Regardless of the spelling variation, it refers to the exact substantial-precision coating method.
five. CVD and PVD Coating
CVD and PVD coating are the two Actual physical vapor deposition approaches used for making use of slender films. Having said that, they differ significantly within their procedures and applications.
CVD (Chemical Vapor Deposition):
Works by using chemical reactions
Normally will involve larger temperatures
Perfect for creating coatings with exceptional conformality
PVD (Actual physical Vapor Deposition):
Makes use of physical procedures like sputtering or evaporation
Generally operates at decrease temperatures
Suitable for decorative coatings and slim movies
six. CVD Diamond Coating
