Abstract: Methods and systems of applying a liquid precursor for a calcium-magnesium-aluminosilicate (CMAS) resistant coating to a turbine engine component are provided. In one embodiment, a method of manufacturing a turbine engine includes spraying a liquid compound, wherein the liquid component is stored with a carrier gas, applying the compound to a component of a turbine engine, such that the compound is disposed on a thermal barrier coating of the component, and forming an oxide layer on the thermal barrier coating of the component. In another embodiment, a system includes a turbine engine component and a sprayer containing a compound and a carrier gas, wherein the sprayer is configured to apply the compound to a thermal barrier coating of the component such that the compound forms an oxide on the thermal barrier coating.

Abstract: A coating system for reducing the tendency for hydrocarbon fluids, such as fuels and oils, to form carbonaceous deposits that adhere to fluid containment surfaces. The coating system combines an outermost layer of platinum with an inner ceramic barrier layer of silica and/or tantala. The platinum layer catalyzes the hydrocarbon fluid to form particles of carbonaceous gum substances, and the ceramic barrier layer seals the containment surface from the hydrocarbon fluid to eliminate attachments points for deposits and inhibit interdiffusion between the platinum layer and the containment surface. The invention also encompasses a coating apparatus and process for depositing the coating system.
