- Base reinforcement (option)
-
Complex processing technology
Details
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.
- Vacuum heat treatment
-
In 1976, SEAVAC developed original vacuum furnace which took the first step in the Coating department. We work on the development of technology for vacuum heat treatment device that correspond with user needs and provides with higher quality services by introducing it to the coating department.

- Coating film stripping
-
The coating film stripping of CVD processing and PVD process are provided by SEAVAC. In particularly, PVD processing is performed at temperatures below 500℃, making it less thermal effects to the base metal, and also reducing the film cost by film stripping reprocessing before the base material is severely damaged.

By adding Al to TiN is coated with improved more abrasion resistance and heat resistance. When operating temperature exceeds 700℃, the Al component and oxygen are combined by frictional heat, and strong Al2O3 is generated on the outermost layer, contributing to further improvement of the lifetime.
