Diamond coating

What is diamond?

The hardest naturally occurring substance in nature, with the chemical formula C, 

is a crystal composed of carbon elements assembled in a tetrahedral structure.

Technical principle: The hot wire chemical vapor deposition is used, the reaction gas methane and hydrogen

 passes through the high temperature tungsten filament, and is ionized into the group which is conducive

 to the deposition of diamond, and the gaseous group is transported to the substrate with a 

certain temperature, and then nucleates and grows on the substrate in the shape of an island, 

and ultimately forms a diamond film on the surface of the substrate.

Diamond coated cutting tools are made of industry-advanced cemented carbide with sub-micron grains, 

 for high wear-resistant machining applications.
