摘要
Methods are presented for depositing an infrared reflective, e.g., silver, containing multi-layer coating onto a substrate to form a coated article. One or more ceramic cathodes are used to deposit a protective layer over the silver layer. The use of the ceramic cathodes eliminates the need for the metal primer layers common in the prior art. Both the infrared reflective layer and a ceramic layer can be deposited in the same coating zone, this coating zone containing sufficient oxygen to provide a substantially oxidized ceramic coating layer without adversely impacting upon the properties of the infrared reflective layer.
