Abstract: Embodiments of the disclosure provide a system including: an enclosure having an interior sized to enclose and the workpiece and form a vacuum and pressurized atmosphere within the interior. A plurality of thermal applicators may be in thermal communication with first and second portions of the interior. First and second thermal applicators may independently heat and cool the first and second portions of the interior. The first thermal applicator may apply a first thermal treatment to a first portion of the workpiece in the first portion of the interior. A second thermal applicator may apply a second thermal treatment to a second portion of the workpiece in the second portion of the interior independently of the first thermal treatment.

Abstract: 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.

Abstract: A method for fabricating thermal barrier coatings. The thermal barrier coatings are produced with a fine grain size by reverse co-precipitation of fine powders. The powders are then sprayed by a solution plasma spray that partially melts the fine powders while producing a fine grain size with dense vertical cracking. The coatings comprise at least one of 45%-65% Yb2O3 the balance zirconia (zirconium oxide), Yb/Y/Hf/Ta the balance zirconia (zirconium oxide) and 2.3-7.8% La, 1.4-5.1% Y and the balance zirconia (zirconium oxide) and are characterized by a thermal conductivity that is about 25-50% lower than that of thermal barrier coatings comprising YSZ. The thermal barrier coatings also are characterized by at least one of excellent erosion resistance, fracture toughness and abrasion resistance.
