Chemical Vapor Deposition (CVD)

Chemical Vapor Deposition (CVD)

Low-temperature chemical vapor deposition (CVD) is a process whereby a chemical precursor is vaporized and deposited onto the substrate to impart extremely dense, non-line-of-sight coatings. Typical CVD processes are high temperature (>1000°C) which limits compatibility of certain materials. IBC’s proprietary low-temperature CVD process remains under 450°C, allowing substrate materials to maintain their mechanical properties that would otherwise be lost in higher temperature processes. Coating thickness can be controlled with extreme precision from 0.5 to 50 microns depending on the substrate.

Benefits of Chemical Vapor Deposition

  • Completely non-line-of-sight deposition for uniform coating of interior features and complex shapes
  • Excellent surface finish will mirror that of the substrate
  • Low temperature which avoids loss of mechanical properties and risk of dimensional distortion
