Abstract: A seal comprises a housing. A coating has at least two layers with a bond layer to be positioned between a housing and a second hard layer. The second hard layer is formed to be harder than the bond layer. The bond layer has a bond strength greater than or equal to 200 psi and less than or equal to 2000 psi. A gas turbine engine, and a method of forming a coating layer are also disclosed.

Abstract: A bi-directional auxiliary lubrication system which allows lubricant to be supplied to moving engine components after a loss of lubricant pressure from a main lubricant tank is disclosed. In a gas turbine engine, the lubrication system may siphon compressed air from a compressor to draw lubricant from a reserve lubricant tank and deliver that lubricant to the engine components. The same conduits used by the lubrication during normal operations are utilized in an opposite direction to provide the flow of lubricant from the reserve lubricant tank during such auxiliary or low-lubricant-pressure operations.

Abstract translation: 公开了一种双向辅助润滑系统，该润滑系统允许润滑剂在主润滑油箱损失润滑剂压力之后供应到移动的发动机部件。 在燃气涡轮发动机中，润滑系统可虹吸来自压缩机的压缩空气以从储备润滑油箱中吸取润滑油并将该润滑油输送到发动机部件。 正常操作期间用于润滑的相同导管被用于相反的方向，以在辅助或低润滑剂压力操作期间提供来自备用润滑油箱的润滑油流。
