Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is often a approach wherein a substrate is exposed to a number of unstable precursors, which react and/or decompose within the substrate surface to create the specified slim film.
Steps in the CVD System:
Precursor introduction
Chemical response and film development
By-solution removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling commonly made use of exterior The us, particularly in British English. Regardless of the spelling variation, it refers to the exact 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 thin films. Nevertheless, they vary considerably inside their processes and programs.
CVD (Chemical Vapor Deposition):
Uses chemical reactions
Generally involves better temperatures
Perfect for generating coatings with fantastic conformality
PVD (Physical Vapor Deposition):
Works by using physical processes like sputtering or evaporation
Normally operates at lower temperatures
Appropriate for attractive coatings and slender films
