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.
Claims11
A method of forming an abradable seal for use between rotating and non-rotating machinery components, wherein the abradable seal has a substrate with a surface upon which an abradable material may be applied and wherein the method comprises the steps of:
- a) providing a sheet of the abradable material having a uniform thickness by:
- 1) forming a mixture of sheet precursor components;
- 2) degassing the mixture;
- and
- 3) pouring the mixture into a compression mold;
- b) cutting the sheet of the abradable material to form at least one abradable sheet piece of a desired shape;
- c) mixing an adhesive component with a spacer material to form an adhesive composition;
- d) applying the adhesive composition over at least a portion of the substrate surface;
- and
- e) contacting the abradable sheet piece with the adhesive composition to adhesively bond the abradable sheet piece to the substrate surface.
