Abstract
An article of manufacture includes a substrate and an anchoring layer disposed on a surface of the substrate. The substrate is capable of developing a first oxide on the surface which is tightly bonded thereto and includes a first metallic element. Alternatively, the surface is formed of the first oxide. The anchoring layer is formed with a ternary oxide of the first metallic element, a second metallic element and oxygen. A second oxide layer, which contains an oxide of the second metallic element, is disposed on the anchoring layer. The anchoring layer is formed on the substrate in a series of process steps, which include: establishing an atmosphere containing oxygen around the article; evaporating a compound of the first metallic element and a compound of the second metallic element into the atmosphere and forming a ternary gas phase containing the first metallic element, the second metallic element and the oxygen; and precipitating the ternary gas phase on the article.
