The invention relates to a process for coating an article (1), wherein a coating (2) having one or more coating layers (3, 4, 5) is applied to the article (1), wherein at least one coating layer (5) is formed essentially from aluminium, titanium and nitrogen, wherein the coating layer (5) has, at least in some regions, adjoining lamellae of different chemical composition and is deposited from a gas phase comprising at least one aluminium precursor and at least one titanium precursor. According to the invention, by setting a molar ratio of aluminium to titanium, the lamellae of different chemical composition are each formed with a cubic structure, it being possible for aluminium and titanium to be partly replaced by other metals and for nitrogen to be partly replaced by oxygen and/or carbon with retention of the cubic structure. The invention further relates to a correspondingly produced coating (2).
A method for coating an object (1), wherein a coating (2) having one or more coating layers (3, 4, 5) is applied to the object (1), wherein at least one coating layer (5) is formed essentially from aluminum, titanium and nitrogen, wherein the coating layer (5) comprises, at least in some regions, mutually adjoining lamellae of varying chemical composition and is deposited from a gas phase having at least one aluminum precursor and at least one titanium precursor, characterized in that, by adjustment of a molar ratio of aluminum to titanium, the lamellae of varying chemical composition are each formed with a cubic structure, wherein with the preservation of the cubic structure, aluminum and titanium can be partially replaced by other metals, and nitrogen can be partially replaced by oxygen and/or carbon.
A coating (2) which is applied to an object (1) by means of a CVD method, wherein the coating (2) comprises one or more coating layers (3, 4, 5) and wherein at least one coating layer (5) is formed essentially from aluminum, titanium and nitrogen and, at least in some regions, comprises mutually adjoining lamellae of varying chemical composition, characterized in that the lamellae of varying chemical composition are each formed with a cubic structure, wherein with the preservation of the cubic structure, aluminum and titanium can be partially replaced by other metals, and nitrogen can be replaced by oxygen and/or carbon.
