ARC COATING OF REFRACTORY METAL COMPOUNDS

A process for arc coating alloy nitride films on objects using a cathode or target (24) composed of separate sections (25, 26) of the two metals from which the alloy is to be formed and a steered arc that is controlled in its path across the target (24) along a controlled arc trajectory to provide a...

Zusammenfassung:	A process for arc coating alloy nitride films on objects using a cathode or target (24) composed of separate sections (25, 26) of the two metals from which the alloy is to be formed and a steered arc that is controlled in its path across the target (24) along a controlled arc trajectory to provide a controlled coating composition with reproducible results. Procédé de revêtement à l'arc d'objets par des films d'alliages de nitrure, utilisant une cathode ou cible (24) composée de parties séparées (25, 26) des deux métaux dont l'alliage doit se composer, ainsi qu'un arc régulé dont on dirige la trajectoire à travers la cible (24) de manière à obtenir une trajectoire contrôlée de l'arc pour former une composition de revêtement contrôlée avec des résultats reproductibles.
