Surface finish
CVD grows a thin, hard film from gas. It adds wear, heat, and corrosion resistance at the microscopic level.
What it is
CVD (Chemical Vapor Deposition) is a process where gases react inside a hot vacuum chamber. They form a solid thin film on the part. Common films are TiN, TiCN, and diamond-like carbon (DLC). CVD coatings are extremely hard and thin, perfect for tools and high-wear parts.
How it works
Load & pump down
The part goes into a vacuum chamber and air is removed.
Heat the part
The chamber is raised to several hundred to 1000 °C.
Introduce gases
Reactant gases flow in and decompose on the hot surface.
Grow the film
A thin, dense coating builds layer by layer.
Cool & unload
The part cools and is removed for inspection.
Why choose it
Films like TiN and DLC resist wear sharply.
Withstands heat better than organics.
Dense film blocks attack.
DLC cuts friction on moving parts.

Our solution
We apply CVD thin films such as TiN, TiCN, and DLC for tools and wear parts. We match the film to your duty cycle and base material.
Design tips
CVD runs hot; confirm your material can take it.
Choose CVD for cutting and sliding wear.
Sharp edges may need rounding before coating.
