Chemical Vapor Deposition (CVD Coating) | Ultramet

Ultramet specializes in the chemical vapor deposition of refractory metals and ceramics. CVD results from the chemical reaction of gaseous precursor(s) at a heated substrate to yield a fully dense deposit. Ultramet uses chemical vapor deposition to apply refractory metals and ceramics as thin coatings on various substrates and to produce freestanding thick-walled structures.
