摘要： This invention relates in part to thermal barrier coating systems that comprise at least one metallic or metallic/ceramic inner layer deposited onto a substrate, at least one ceramic intermediate layer deposited onto the inner layer, and at least one ceramic outer layer deposited onto the intermediate layer. The ceramic intermediate layer is a thermally sprayed coating having a plurality of macrocracks distributed throughout the intermediate layer. The ceramic outer layer is a thermally sprayed coating made from composite ceramic powder particles that include a zirconia-based component and an (alumina+silica)-based component. The ceramic outer layer is substantially free of macrocracks. This invention also relates in part to methods of forming thermal barrier coating systems, and articles coated with thermal barrier coating systems. The thermal barrier coating systems are suitable for protecting components exposed to high temperature environments, such as the thermal environment of a gas turbine engine.

摘要： The invention relates to gas turbine engine seal systems having a rotating member with an abrasive tip surface disposed in rub relationship to a stationary seal member with an abradable surface. The abrasive tip surface is coated with a metallic alloy matrix having ceramic abrasive particles embedded in and projecting from the matrix. The abradable seal surface is coated with a ceramic coating. The rub relationship affords a tight operating clearance between the rotating member and the stationary seal member, thereby improving engine efficiency, reducing fuel consumption and minimizing overhaul downtime.
