Technical Information

What is Diamond Coating System?

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’s Diamond Coating System

By using the hot filament CVD method, it is possible to synthesize diamond over a large area, making it possible to apply it to mass-produced products such as coating cutting tools.
We use our own technology to optimize adhesion and also provide conductive diamond coating. We also sell equipment and undertake contract development.
In addition, by utilizing our ion etching technology, we can also propose recycling methods such as film removal and recoating.

Application

Cutting tools for CFRP, Graphite and Aluminum processing
Dies & Molds
Seal component
Electrode

The small dedicated machine SDC100 can also be modified to fit special shapes such as molds.

* Due to diamond coating temperature will be around from 800degC to 900degC, substrate material shall be
limited heat-resistant material.
For coating on cobalt content carbide, de-cobalt pretreatment is required.
Also our pretreatment system can be offered as turnkey.
Optimized diamond grain size can be offered for each applications.

We also offer polishing techniques after diamond deposition.

We can also propose microwave plasma CVD equipment.
