摘要: Poly-p-xylylene is utilized for a thin conformal dielectric coating on metallized discs. The poly-p-xylylene coating is deposited by vapor deposition and then hardened by exposure to a glow discharge. A method of hardening a polymeric dielectric coating by exposure to a glow discharge after the coating has been deposited on the disc.
