METHOD OF PRODUCING AN ABRASIVE TIP FOR A TURBINE BLADE

A method of producing an abrasive tip for a turbine blade (150) includes producing or obtaining a metal powder that is mixed with an abrasive ceramic powder and producing or obtaining a metallic mold (200) that is in the shape of an airfoil (152). The metallic mold (200) includes a hollow interior p...

Beschreibung
Zusammenfassung:	A method of producing an abrasive tip for a turbine blade (150) includes producing or obtaining a metal powder that is mixed with an abrasive ceramic powder and producing or obtaining a metallic mold (200) that is in the shape of an airfoil (152). The metallic mold (200) includes a hollow interior portion. The method further includes sealing the metal and ceramic powder mixture within the hollow interior portion of the metallic mold under vacuum and subjecting the sealed mold to a hot isostatic pressing process. The hot isostatic pressing process compacts and binds the metal and ceramic powder mixture together into a solid article in the shape of the airfoil. Still further, the method includes slicing the solid article into a plurality of airfoil-shaped slices and bonding one slice of the plurality of airfoil-shaped slices to a tip portion of a turbine blade.
