    Abstract: A cathodic sputtering operation using a target of a material containing titanium, aluminium, oxygen and nitrogen in an argon atmosphere is disclosed.This sputtering operation gives rise to a layer containing the same elements as the target. The resulting layer is opague, has an attractive, deep and brilliant black color, adheres well to the substrate and is resistant to wear and corrosion. The physical structure of the layer is characterized by a transparent and insulating amorphous phase in which are dispersed a plurality of inclusions having a size on the order of nanometers.
