AI Technical Summary

Problems solved by technology

Upon cooling, infiltrated deposits solidify, possibly causing delamination and / or spalling of the coating
Similarly, unmelted contaminant deposits may penetrate such pores, channels, cracks or other cavities in the coating and similarly cause the coating to delaminate and / or flake

Embodiment

[0089] Various slurry suspensions including silicates were prepared and used to form an easy coating 102 on the substrate. Exemplary slurry suspensions contain silica dispersed in ethanol, 20% by weight of solids. Another exemplary slurry suspension comprises silica and a silicate. The resulting slurry suspension was applied to the surface of the sample, the sample included a rare earth-diosilicate barrier coating on a silicon carbide substrate, provided on the surface of the rare earth-diosilicate barrier coating 1 -MIL thick-consuming coating. Two-layer easy coating is also formed. Exemplary two-layer compulsive coating includes a first layer comprising silica and a second layer comprising silicate. In some embodiments, the first layer is applied to the sample, and the second layer is applied to the first layer, in some embodiments, the second layer is applied to the sample, and the first layer is applied On the second layer. An exemplary viable coating comprises silica, rare ea...

Abstract

A coated component may have a consumable coating that protects the component from dust. The coated component may include a silicon containing substrate defining a substrate surface, a barrier coating on the substrate surface, with the barrier coating defining a barrier surface, and a consumable coating on the barrier surface. The consumable coating may include a ceramic oxide that includes a silicate. A component, such as a component of a turbomachine, may be protected from dust by applying a consumable coating on the component.

Description

Technical field [0001] Embodiments of the present invention generally relate to a viable coating for protecting a barrier coating on a component used in a high temperature system such as a turbine, and is formulated and applied to protect such components from Methods of damage to dust deposit. Background technique [0002] In order to improve the efficiency of the turbine, a higher operating temperature of the turbine has been seeking. However, as the operating temperature rises, the high temperature durability of the engine member must be improved accordingly. The formulation of iron, nickel and cobalt-based high-temperature alloys has achieved significant advancement of high temperature performance. Further, for many hot air passage components made of a high temperature alloy, the heat insulating coating (TBC) can be used to insulate these components, and the structural components can be limited between the load-bearing alloy and the surface of the coating. Hot exposure. [000...
