    Abstract: Different types of apparatus (10, 50) for fabricating a deposit (12, 86), method of deposition and an article (80) are presented. The apparatus (10) include a thermal spray gun (16) comprising a combustion chamber (22), combustion zone (28), an air injection port (18), a fuel injection port (20), a nozzle (30) and a liquid injection port (34). The combustion zone (28) exists between the inlet side (24) and outlet side (26) of the combustion chamber (22). The method includes, among other things, providing a fuel and an oxidizer inside the combustion zone (28), initiating combustion inside the combustion zone (28), and directing products of the combustion toward the outlet side (26) to create a combustion product stream. The method also includes introducing a feedstock mixture comprising a feedstock material and a liquid into the combustion product stream to create an entrained feedstock stream, and expelling the entrained feedstock stream from the spray gun through a nozzle to form a deposit on a surface of the article.

    Abstract: A thermal barrier coating system (20) for metal components (22) in a gas turbine engine having an ultra low thermal conductivity and high erosion resistance, comprising an oxidation-resistant bond coat (24) formed from an aluminum rich material such as MCrAlY and a thermal insulating ceramic layer (26) over the bond coat (24) comprising a zirconium or hafnium oxide lattice structure (ZrO 2 or HfO 2 ) and an oxide stabilizer compound comprising one or more of the compounds ytterbium oxide (Yb 2 O 3 ), yttrium oxide (Y 2 O 3 ), hafnium oxide (HfO 2 ), lanthanum oxide (La 2 O 3 ), tantalum oxide (Ta 2 O 5 ) or zirconium oxide (ZrO 2 ). The invention includes a new method of forming the ceramic-based thermal barrier coatings using a liquid-based suspension containing microparticles comprised of at least one of the above compounds ranging in size between about 0.1 and 5 microns. The coatings form a tortuous path of ceramic interfaces that increase the coating toughness while preserving the ultra low thermal conductivity.

    Abstract: A process by which a ceramic coating (14) is entirely formed from a colloidal-based process to have a thickness that would ordinarily be prone to cracks and spallation involves forming a precursor primer layer on a surface region (12,16,18), and then forming at least a precursor coating layer on the precursor primer layer that is thicker than the precursor primer layer. The precursor primer layer contains particles and a precursor of a first ceramic material. The precursor coating layer contains particles and a precursor of a second ceramic material having the same predominant constituent as the first ceramic material. The precursor primer layer and precursor coating layer are then heated to form a ceramic film (20) and a ceramic coating layer (14), respectively, which consist essentially of the particles and matrices of, respectively, the first and second ceramic materials.

    Abstract: A process capable of depositing a diffusion coating of uniform thickness on localized surface regions of a component. The process makes use of an adhesive mixture containing a binding agent that is consumed as part of the deposition process so as not to negatively affect the quality and uniformity of the resulting coating. The process entails mixing a particulate donor material containing a coating element, a dissolved activator, and a particulate filler to form an adhesive mixture having a formable, malleable consistency. The adhesive mixture is applied to a surface of the component, and the component is heated to a temperature sufficient to vaporize and react the activator with the coating element of the donor material, thereby forming a reactive vapor of the coating element. The reactive vapor reacts at the surface of the component to form a diffusion coating containing the coating element.
