- Base reinforcement (option)
Complex processing technologyDetails
In general, CVD is “bonding” by chemical reaction, whereas PVD is “evaporation” by collision energy, so the adhesion is generally inferior.
In order to improve the adhesion of PVD, it is effective to reduce the difference of hardness between the base material surface and the coating film. The difference is expanded especially with the increasing hardness of PVD. Therefore, SEAVAC adapted following technology as the base reinforcement.
