Abstract:
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.
