What is Diamond Coating?

Diamond is the most stiff material in existing materials, and it is a very excellent substance in mechanical, electrical, chemical and thermal conductivity. Diamond can be provided as a coating, it can be contributed in various fields, so research and development is proceeding.
As a method of synthesizing diamond, high pressure high temperature method(HPHT), hot filament CVD method, and microwave plasma CVD method, etc. are available, and from various excellent characteristics such as improvement of wear resistance of cutting tool and improvement of durability of electrolytic electrode application is expected.

ShinMaywa Diamond Coating System

Adopting the hot filament CVD method, diamond can be synthesized on a large area, and it can be applied to mass production products such as coating on cutting tools.
Adopting the hot filament CVD method, diamond can be synthesized on a large area, and it can be applied to mass production products such as coating on cutting tools.
Unique technology optimizes adhesion and also offer conductive diamond coating.
We can propose the system sales and also coating service.
In addition, we can propose recycling such as film removal and re-coating by taking advantage of our ion etching technology.
