A coated article is provided with at least one infrared (IR) reflecting layer. The IR reflecting layer may be of silver or the like. In certain example embodiments, a titanium oxide layer is provided over the IR reflecting layer, and it has been found that this surprisingly results in an IR reflecting layer with a lower specific resistivity (SR) thereby permitting thermal properties of the coated article to be improved.

A method of manufacturing a glass article comprising: forming a first layer of a first metal on a glass substrate, the glass substrate comprising silicon dioxide and aluminum oxide; subjecting the glass substrate with the first layer of the first metal to a first thermal treatment; forming a second layer of a second metal over the first layer of the first metal; and subjecting the second layer of the second metal to a second thermal treatment, the first thermal treatment and the second thermal treatment inducing intermixing of the first metal, the second metal, and at least one of aluminum, aluminum oxide, silicon, and silicon dioxide of the glass substrate to form a metallic region comprising the first metal, the second metal, aluminum oxide, and silicon dioxide. The first metal can be silver. The second metal can be copper.

The invention provides a glazing sheet and a coating on the glazing sheet. The coating comprises, in sequence moving outwardly from the glazing sheet, a dielectric base coat comprising oxide film, nitride film, or oxynitride film, a first infrared-reflective layer, a first nickel-aluminum blocker layer in contact with the first infrared-reflective layer, a first dielectric spacer coat comprising an oxide film in contact with the first nickel-aluminum blocker layer, a second infrared-reflective layer, a second nickel-aluminum blocker layer in contact with the second infrared-reflective layer, a second dielectric spacer coat comprising an oxide film in contact with the second nickel-aluminum blocker layer, a third infrared-reflective layer, a third nickel-aluminum blocker layer in contact with the third infrared-reflective layer, and a dielectric top coat comprising an oxide film in contact with the third nickel-aluminum blocker layer. Also provided are methods of depositing such a coating.

Device and method for producing defined properties of gradient layers in a system of multilayered coatings in sputtering installations with the following features: a) a pair of cathodes arranged in a common process chamber and consisting of a first cathode body and a second cathode body is supplied with direct current by means of a common power supply, wherein, before entering the process chamber, the direct current is converted into a series of pulses comprising alternating positive and negative pulses with interpulse periods in between, b) an arrangement for controlling the length of the individual pulses and the duration of the respective interpulse periods.

An ellipsometry system detects and/or identifies significant corrosion on glass, such as on soda-lime-silica based float glass. In certain example embodiments, there is provided a method and/or system using ellipsometry to detect and/or identify significant corrosion on soda-lime-silica based glass, so that such significantly corroded glass can be identified and not coated with a low-E coating and/or not used in applications where optical appearance is important. The ellipsometry system may be part of, or used in connection with, a sputtering apparatus/system for sputter-depositing low-E coatings on glass, so that whether to pass a piece of glass to the sputtering apparatus/system is based on whether significant corrosion is detected on the glass.

The invention provides a glazing sheet and a low-emissivity coating on the glazing sheet. The low-emissivity coating comprises, in sequence moving outwardly from the glazing sheet, a layer comprising oxide film, nitride film, or oxynitride film, an infrared-reflective layer, a nickel-aluminum blocker layer, and an oxide layer. Also provided are methods of depositing such a low-emissivity coating.
