Abstract
The present invention provides a method of forming an abradable seal between rotating and non-rotating components of a machine. A sheet of abradable material is formed and then cut to a desired shape to form an abradable sheet piece. An adhesive composition is applied to at least a portion of a substrate surface and the sheet piece is contacted with the adhesive composition to adhesively bond the sheet piece to the substrate to form the abradable seal. An abradable seal is also provided having an adhesive composition deposited over at least a portion of a substrate surface with an abradable sheet piece bonded to the substrate by the adhesive composition.
