Embodiments described herein provide methods of forming amorphous or nano-crystalline ceramic films. The methods include depositing a ceramic layer on a substrate using a physical vapor deposition (PVD) process, discontinuing the PVD process when the ceramic layer has a predetermined layer thickness, sputter etching the ceramic layer for a predetermined period of time, and repeating the depositing the ceramic layer using the PVD process, the discontinuing the PVD process, and the sputter etching the ceramic layer until a ceramic film with a predetermined film thickness is formed.

A protective coating for a copper alloy substrate includes a layer of a transition metal, referred to as primer layer, and a corrosion protection layer formed by at least one portion of the primer layer. The primer layer includes the transition metal combined with an oxidized transition metal. A process for depositing the protective coating is by physical vapor deposition (PVD) technology. The substrate is positioned in a chamber, with a target made of a transition metal, the chamber being supplied with various gases. The substrate is dehumidified and descaled. A thin primer layer of transition metal is deposited on substrate and bombarded with a mixture of argon ions and oxygen ions. A corrosion protection layer is formed by oxidizing the transition metal of the primer layer.

A film forming method includes performing a process including a) and b) a plurality of times, with a) being performed before b) in the process: a) supplying borazine-based gas to a substrate, thereby adsorbing the borazine-based gas to the substrate and b) exposing the substrate to a nitrogen plasma.

A method for producing an AlCrO-based coating on a workpiece surface, including: a) placing a workpiece in an interior of a vacuum chamber, and b) depositing a film comprising aluminum and chromium on the workpiece surface to be coated, wherein a ratio of aluminum to chromium in the film in atomic percentage has a first value corresponding to Al/Cr?2.3, and c) forming volatile compounds of CrO, thereby causing at least part of the chromium contained in the film to leave the film in a form of CrO volatile compounds, and d) executing step c) during a period of time, within which the chromium content in the film is reduced until attaining a second value of the ratio of aluminum to chromium in the film in atomic percentage corresponding to Al/Cr?3.5, thereby the film is transformed into a film containing a reduced content of chromium.

Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that a combination of substrate layers and insulation layers is configured to provide improved thermal insulation. The fabric composites are constructed to form a radiant barrier against heat loss via radiation and via conduction from a body.

A transparent electrode-equipped substrate includes a metal oxide transparent electrode layer on a transparent substrate. The average maximum curvature Ssc of the surface of the transparent electrode layer is preferably 5.410.sup.4 nm.sup.1 or less. For example, if the transparent electrode layer is subjected to a surface treatment by low discharge-power sputtering after deposition, the Ssc of the transparent electrode layer can be reduced. This transparent electrode-equipped substrate excels in close adhesion between the transparent electrode layer and a lead-out wiring line disposed on the transparent electrode layer. The transparent electrode layer is obtained by, for example, performing a transparent electrode deposition step of through the application of a first discharge power and then performing a surface treatment step through the application of a second discharge power.
