Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is really a approach whereby a substrate is subjected to one or more unstable precursors, which react and/or decompose about the substrate floor to generate the specified slender movie.
Ways within the CVD Approach:
Precursor introduction
Chemical reaction and film formation
By-product removing
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling frequently applied exterior The usa, notably in British English. Despite the spelling variation, it refers to the very same superior-precision coating system.
