Abstract: A control system includes one or more processors configured to determine when to extend a life span of an engine by applying an additional restorative coating to the engine based on one or more monitored parameters of the engine. The monitored parameters include a condition of a previously applied restorative coating. The one or more processors are configured to determine the condition of the previously applied restorative coating based on an optical response of the previously applied restorative coating. The one or more processors also are configured to direct application of the additional restorative coating based on the one or more monitored parameters of the engine.

Abstract: An article for service at high temperatures comprises a substrate comprising a first region and a second region; and a coating disposed over the substrate. The coating comprises a first portion disposed over the first region of the substrate and a second portion disposed over the second region of the substrate. The coating includes a layer comprising a ceramic material and further including a quantity of surface-connected voids, and a protective agent is disposed within at least some of the surface-connected voids of the layer. Within the first portion, the agent is present within the layer at a concentration of less than or equal to 4 percent by volume of the layer exclusive of the voids, while, within the second portion, the agent is present within the layer at a concentration up to the carrying capacity of the layer. Methods for forming the article are also presented.

Abstract: Articles having coatings that are resistant to high temperature degradation are described, along with methods for making such articles. The article comprises a coating disposed on a substrate. The coating comprises a plurality of elongated surface-connected voids. The article further includes a protective agent disposed within at least some of the voids of the coating; the protective agent comprises a substance capable of chemically reacting with liquid nominal CMAS to form a solid crystalline product outside the crystallization field of said nominal CMAS. This solid crystalline product has a melting temperature greater than about 1200 degrees Celsius. The method generally includes disposing the protective agent noted above within the surface connected voids of the coating at an effective concentration to substantially prevent incursion of CMAS materials into the voids in which the protective agent is disposed.

Abstract: Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A gas and a slurry that comprises fluid and ceramic particles are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.

Abstract: An article having a damage-tolerant thermal barrier coating includes a plurality of coating layers disposed over a substrate. The plurality of coatings comprises an inner layer and an outer layer. The outer layer is more resistant to infiltration by nominal CMAS relative to 8 weight percent yttria-stabilized zirconia at a temperature of 1300 degrees Celsius. The inner layer has, in a temperature range from about 1000 degrees Celsius to about 1200 degrees Celsius, a thermal resistance in a range from about 9×10−5 degree Kelvin per watt to about 23×10−5 degree Kelvin per watt.
