Only few can answer this question better than the experts at voestalpine eifeler coating. Since 1983, we have not only been engaged in coating of surfaces, but also continuously set new standards in research and development. It’s therefore no surprise, that today eifeler technology is synonymous with high-tech and premium products.
We cover the entire value chain from polishing to PVD and CVD coating.
PVD coatings are created in a high vacuum by converting metal into a vaporous state and simultaneously adding a reaction gas. With different temperatures (starting from 200 °C) we can deposit layers of 2-8 µm.
Our in-house research and development department has developed numerous successful PVD coatings in recent years and presented them to the market. All developments have always resulted from market and customer needs. With several centuries of experience in the tooling industry, we have a deep insight into the entire value chain, which extends from the material selection to the finished tool.
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. Due to the very good adhesive strength and, at the same time, very high hardness, these layers are also called heavy-duty.
High-alloy tool steels, HSS and PM materials and 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.
