Coating system for a substrate comprises a layer of refractory metal-magnesium nitrides

Coating system comprises a layer of refractory metal-magnesium nitrides. An independent claim is also included for a process for the production of the coating system comprising applying a refractory metal-magnesium nitride layer using a PVD method. Preferred Features: Intermediate layers are applied...

Beschreibung
Zusammenfassung:	Coating system comprises a layer of refractory metal-magnesium nitrides. An independent claim is also included for a process for the production of the coating system comprising applying a refractory metal-magnesium nitride layer using a PVD method. Preferred Features: Intermediate layers are applied between the substrate and refractory metal-magnesium nitride layer. The intermediate layers are made from a nitride, carbide, boride, oxide, oxynitride, carbonitride or boron carbonitride of a refractory metal or magnesium refractory metal. Dekorative Beschichtung zum Schutz eines Substrates vor Korrosion, Verschleiß und Oxidation auf der Basis von Refraktärmetall-Magnesium-Nitriden. Zum Zwecke einer Verbesserung der Haftung der Refraktärmetall-Magnesium-Nitrid-Beschichtung (30) zum Substrat (10) werden eine oder mehrere Zwischenschichten (20, 21, 22), vorzugsweise abwechselnd bestehend aus Refraktärmetall und Refraktärmetallnitrid oder aus Refraktärmetall-Magnesium, aufgebracht. Eine oder mehrere Abschlußschichten (40) erfüllen dekorative Zwecke (Metallnitride, Metallkarbide, Metallkarbonitride, Metalloxynitride) oder dienen der Verschleiß- und Reibwertminderung (Hartstoffschichten, Festschmierstoffe). Alle beschriebenen Schichten werden mittels Physical Vapour Deposition (PVD) oder Chemical Vapour Deposition (CVD) Verfahren hergestellt.
