PVD coating (Physical Vapour Deposition) is a vacuum supported process for the manufacture of metallic or oxide/ nitride films, with film thicknesses of up to approx. 5 µm. These are mainly functional film layers with special contact or corrosion protection properties.
Based on our long years of experience in the processing and finishing of metallic materials, our own target and ingot manufacture as well as the enormous diversity of coating processes that we have at our disposal, W. C. Heraeus develops tailor-made and flexible solutions for the widest range of applications.
One of the important advantages of PVD coating is that the substrate is subjected to absolutely no chemical and only minimal thermal effects. W. C. Heraeus applies coatings of both pure elements and chemical compounds such as oxides, fluorides and sulphides.
The spectrum of coatable geometries and materials and the resulting range of applications are extremely diverse. Our flexibility, the expertise in precious metal and the availability of top quality raw materials also enables us to carry out test projects in a comprehensive format and in small series – ideal conditions for the use of coatings in future oriented applications.
