Preparation Cemented Carbide Coated Tool

Preparation cemented carbide coated tool varied, its methods are vapor deposition, thermal spraying, chemical treatment, thermal reaction diffusion deposition, sol-gel. Is a method commonly used in the preparation of vapor deposition, because the preparation of the coating quality is good, has gradually become the dominant tool coating preparation methods, vapor deposition, chemical vapor deposition technology is divided into (chemicalvapordeposition, CVD) and physical vapor deposition (physicalvapordeposition, PVD). Chemical vapor deposition (CVD) deposition category belonging atom, a pioneer in the use of gaseous reactants through the atom generated solid coating, intermolecular chemical reaction pathway techniques.
