  • Patent number: 10597776
    Abstract: 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).
    Type: Grant

  • Patent number: 9636750
    Abstract: The invention relates to a body, especially a cutting element, at least partially comprising a coating, whereby the coating is formed from one or more coating layers, whereby at least one coating layer comprises aluminum, titanium and nitrogen or is formed from these elements. According to the invention, the coating layer with aluminum, titanium and nitrogen at least partially comprises lamellae having a lamellar thickness of less than 100 nm, whereby the lamellae comprise successive sections having different phases. The invention further relates to a method for coating a body, especially a cutting element.
