SiC Coating PERMA-KOTE

A dense layer of silicon carbide (SiC) is created via chemical vapor deposition (CVD)。

  • ・Protects substrate from ambient environment
  • ・Controls generation of particles and gas from substrate
  • ・Allows modification, etc. of substrate surface
  • ・Maximum dimensions:Φ1050X830H
Article Conditions for SiC Coating
