Base reinforcement (option)
Base reinforcement (option)

Complex processing technology

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.

Vacumn heat treatment
Vacumn 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
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.

TiN coating
TiN coating

As a standard for titanium coating, it is widely used for cutting tools such as drills and cutters, and decorations. It is also suitable for die molds with tight dimensional tolerances.

DLC coating
DLC coating

Diamond-Like Carbon as named, with a carbon film having the properties such as diamond, other metal elements based PVD and has a different nature.

TiCN-PVD coating
TiCN-PVD coating

This coating has improved hardness by adding carbon (C) to TiN . Since the film thickness is almost same as TiN , it can be easily adopted as a upgrade version of TiN.

CrN coating
CrN coating

This is the standard for chrome coating and has excellent adhesion resistance, corrosion resistance, and slidability. The component elements are stable and may be used as a base for other coatings to prevent corrosion.

S-PVD(TiN) coating
S-PVD(TiN) coating

It is our long hit product that further improves the impact resistance and wear resistance of TiN. It achieves both high hardness and thickening, and supports long tool life and high surface pressure.

TiAln coating
TiAln coating

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.

ZEROⅠcoating
ZEROⅠcoating

Developed newly ZERO-I ( Zero One) coating from the existing PVD Coating for higher hardness, heat resistance and lubricity . Superior wear resistance contributes to longer life.
