CVD coatings: individual for your application

A CVD coating (Chemical Vapor Deposition) describes the deposition of hard material layers in a chemical gas phase process. At temperatures of approx. 1000 ° C, the gaseous layer components flow around the tool and react with elements from the tool surface to form a layer with very high adhesive strength.

The layer systems (TiC, TiN / TiC or TiC / TiN) grow with a layer thickness of 7-10 µm. Due to the very good adhesive strength and, at the same time, very high hardness, these layers are also called heavy-duty. The chemical process also enables the coating of holes and undercuts to be reproducible.

This technology still has its place in industrial applications, just like in our product portfolio. High-alloy tool steels, HSS and PM materials and also hard metals are coated. Steel tools must be subjected to a post-heat treatment after coating. This must take place in a vacuum, which is why the hardenability in a vacuum is a mandatory requirement for the tool steels to be used.

The choice of material and the processing steps to be coordinated with the CVD coating are an important issue, especially because of the required post-heat treatment. With more than 30 years of know-how, we are happy to advise you.
