Summary:PROBLEM TO BE SOLVED: To provide a method of reducing air leakage in a power generation system including a self-lubricating brush seal assembly (18) and a plurality of self-lubricating members (30).SOLUTION: The plurality of self-lubricating members (30) include a plurality of self-lubricating bristles (42), a plurality of cores (52) sheathed in a self-lubricating braid (54), the plurality of cores (52) having an outer diameter (56) coated with a self-lubricating material (62) and a solid lubricating pack (80). The lubricating material is selected from graphite, hexagonal-boron nitrite (hBN), molybdenum disulfide (MoS2), tungsten disulfide (WS2), titanium nitride (TiN), titanium aluminum nitride (TiAlN), titanium carbonitride (TiCN), and combinations thereof.
