摘要: A core insert for a glass molding machine includes substrate and protective film. The is made of ceramic, such as tungsten carbide (WC), carborundum (SiC), silicon nitride (Si 3 N 4 ), or boron (BNC). film deposited on surface the substrate, fullerene (C 60 C 70 ). has good adhesion between film, because with ceramic material. Thus long working lifetime. method making also provided.
