Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) can be a process wherein a substrate is subjected to one or more unstable precursors, which respond and/or decompose within the substrate surface area to make the desired skinny film.
Measures in the CVD Process:
Precursor introduction
Chemical response and movie development
By-product elimination
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is yet another spelling typically applied exterior America, specifically in British English. Despite the spelling variation, it refers to the exact significant-precision coating course of action.
five. CVD and PVD Coating
CVD and PVD coating are equally physical vapor deposition procedures useful for making use of slender films. However, they differ substantially of their processes and purposes.
CVD (Chemical Vapor Deposition):
Makes use of chemical reactions
Generally requires increased temperatures
Ideal for creating coatings with superb conformality
PVD (Actual physical Vapor Deposition):
Takes advantage of Actual physical procedures like sputtering or evaporation
Frequently operates at reduce temperatures
Well suited for attractive coatings and thin films
