Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is really a process whereby a substrate is subjected to one or more risky precursors, which respond and/or decompose within the substrate surface to produce the specified skinny film.
Ways from the CVD Course of action:
Precursor introduction
Chemical reaction and movie formation
By-item removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling usually utilised outside America, specially in British English. Despite the spelling variation, it refers back to the identical high-precision coating course of action.
