    摘要： A coating method, coated article and coating are provided. The coated article includes a low temperature component, and a graphene coating formed from a graphene derivative applied over the low temperature component. The coating method includes providing a graphene derivative, providing a low temperature component, applying the graphene derivative over the low temperature component, and forming a graphene coating. The graphene coating reduces corrosion and fouling of the low temperature component. The coating includes a graphene derivative, and modified functional groups on the graphene derivative. The modified functional groups increase adherence of the coating on application to a low temperature component.

    摘要： A process of fabricating a thermal barrier coating is disclosed. The process includes cold spraying a substrate (101) with a feedstock (402) to form a thermal barrier coating (102) and concurrently oxidizing one or more of the substrate (101), the feedstock (402), and the thermal barrier coating (102). The cold spraying is in a region (103) having an oxygen concentration of at least 10%. In another embodiment, the process includes heating a feedstock (402) with a laser (411) and cold spraying a substrate (101) with the feedstock (402) to form a thermal barrier coating (102). At least a portion of the feedstock (402) is retained in the thermal barrier coating (102). In another embodiment, the process of fabricating a thermal barrier coating includes heating a substrate (101) with a laser (411) and cold spraying the substrate with a feedstock to form a thermal barrier coating.

    摘要： A process (101) of forming a calcium-magnesium-aluminosilicate (CMAS) penetration resistant coating, and a CMAS penetration resistant coating are disclosed. The process includes providing a thermal barrier coating (110) having a dopant (112), and exposing the thermal barrier coating (110) to calcium-magnesium-aluminosilicate (114) and gas turbine operating conditions. The exposing forming a calcium-magnesium-aluminosilicate penetration resistant layer (201). The coating includes a thermal barrier coating composition (110) comprising a dopant (112) selected from the group consisting of rare earth elements, non-rare earth element solutes, and combinations thereof. Additional or alternatively, the coating includes a thermal barrier coating (110) and an impermeable barrier layer or a washable sacrificial layer positioned on an outer surface of the thermal barrier coating.

    摘要： 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.
