PVD hard coatings and metal films
Hard- and metal films are used for various applications
Hard coatings are often nitrides, carbides, oxides or borides of various metals. Typical applications are e. g. wear protection for tools (cutting tools, forming tools) and components (machine components). The conventional hard coatings – like TiN, CrN or ZrN – have been completed in the last years by multi component systems (AlTiN, AlCrN) and recently by nanostructured systems (e.g. TiSiN etc., CrSiN, super lattice films). They have partial significant advantages concerning mechanical properties and temperature stability compared with classical hard coatings.
Nearly all metals can be deposited by PVD. Typical applications are e.g. barrier layers, wear protection, decorative and optical applications, solderable films as well as tribological applications. The IWS practices application oriented research in the field of film- and application development.
