Oerlikon Balzers, a thin film coatings division of the Swiss company Oerlikon, has opened an aerospace industry competence center near Paris. It will be expanding the range of units and components used for PVD (physical vapor deposition) coating.
According to the management of the division, PVD-coatings are becoming more common in aircraft industry, namely, in such components as turbine blades, stabilizers, gear legs, brake systems and engines. The experts of Oerlikon Balzers evaluate the prospective market for this technology in dozens of millions of components and units.
Oerlikon Balzers coatings considerably improve the productivity and replace the environmentally harmful chroming technology. The aircraft makers will be able to improve such parameters as weight of the key components and units while enhancing their reliability, safety and service life.
Physical vapor deposition (PVD) is spraying the coating in vacuum by means of direct condensation of steam of the applied material. PVD-process is used for creating functional coating on the surfaces of components, tools and equipment – resistant to wear, corrosion, erosion, friction, etc. The following materials are used for coating: titanium, aluminum, wolfram, molybdenum, iron, nickel, copper, graphite, chrome and their alloys, as well as acetylene (for coatings containing carbon) and nitrogen. PVD allows application of coating with thicknesses up to 5µm. Typically, the surface does not require any additional treatment after PVD. PVD technology is environmentally friendly.
Oerlikon – is one of the world leaders in production of vacuum systems, equipment for synthetic fiber products, units and components for drives and transmissions, thin film coatings. It has 150 facilities and service centers in 38 countries.
