摘要:
Thermal spray coating methods and thermal spray coated articles are disclosed. The thermal spray coating method includes positioning a covering on a cooling channel of a component, and thermal spraying a feedstock onto the covering. The covering prohibits the feedstock from entering the cooling channel in the component and is not removed from the component. In another embodiment, the thermal spray coating method includes providing a component comprising a substrate material, providing a cooling channel on a surface of the component, positioning a covering on the cooling channel, and thermal spraying a feedstock onto the component and the covering, the feedstock comprising a bond coat material. The covering prohibits the bond coat material from entering the cooling channel. The thermal spray coated article includes a component, a cooling channel, a covering on the cooling channel, and a thermally sprayed coating on the component and the covering.

A method for forming an oxide film by plasma electrolytic oxidation includes a first step of placing an anode, which is a substrate with a conductive nitride film, and a cathode into an electrolyte of which the temperature range is from 20° C. to 100° C., and a second step of applying a voltage ranging from 50 V to 1000 V to the anode and cathode to finally form an oxide film on a surface of the conductive nitride film of the anode. The oxide film can be formed more rapidly than the prior art and has excellent crystallinity.

In certain examples, heat treatable coated articles, e.g., suitable for concentrating solar power (CSP) and/or other applications, may be provided. For instance, the heat treatable coated article may be a secondary reflector panel, primary reflector, etc., where a reflective coating is disposed on a glass substrate. A portion of the reflective coating may be removed and a frit material is disposed over the reflective coating. An elevated temperature may be applied to the glass substrate, the coating, and the frit material where the frit is cured. The coated article may be left flat, or optionally cold- or hot-bent into a desired shape suitable for a desired application.
