Silicon carbide (SiC)
Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) can be a approach wherein a substrate is subjected to a number of volatile precursors, which respond and/or decompose over the substrate floor to create the desired slender movie.
Methods inside the CVD Procedure:
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 usa, especially in British English. Regardless of the spelling variation, it refers to the same significant-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. However, they differ noticeably within their procedures and applications.
CVD (Chemical Vapor Deposition):
Takes advantage of chemical reactions
Normally will involve larger temperatures
Perfect for creating coatings with great conformality
PVD (Bodily Vapor Deposition):
Makes use of Actual physical processes like sputtering or evaporation
Frequently operates at lower temperatures
Appropriate for decorative coatings and slim movies
six. CVD Diamond Coating
